SDK Logging
Overview
This page documents the logs printed by the SDK and features to support enabling and writing logs to a file in the event troubleshooting needs to occur.
Customize SDK Log Levels
The OneTrust SDK supports the ability to customize log types printed to the console. You can control this log level by passing in your preferred minimum log level.
// Swift
OTPublishersHeadlessSDK.shared.enableOTSDKLog(.debug)
// ObjC
[OTPublishersHeadlessSDK.shared enableOTSDKLog:debug];
| Log Level | Description |
|---|---|
OTLoggerConstant.error | Logs only errors. |
OTLoggerConstant.warning | Logs warnings and everything above. |
OTLoggerConstant.info | Logs info and everything above. |
OTLoggerConstant.debug | Logs debug and everything above. |
OTLoggerConstant.verbose | Logs verbose and everything above. |
OTLoggerConstant.noLogs | Turns off all SDK logging. |
Write SDK Logs to a File
The OneTrust SDK supports the ability to write debug logs to file in the event of an issue where the OneTrust team needs to support. Enabling SDK verbose logging will write all the SDK logs to OTPublisherHeadlessSDKLogs.txt file under Document Directory.
// Swift
OTPublishersHeadlessSDK.shared.writeLogsToFile(true, debugLog: true)
// ObjC
[OTPublishersHeadlessSDK.shared writeLogsToFile:true debugLog:true];
| Parameter | Description |
|---|---|
| writeLogs | Logs will only be written to file when passed as true |
| debugLog | Passing true will write all types of logs to the file. Passing false will omit all log types other than error, warning, and info. |
Error Logs
| Error Code | Description |
|---|---|
| 5 | Thrown when invalid language code passed during startSDK() call. Note: This error code is deprecated. The startSDK() method will fallback to en language code when not specifically passed on latest SDK versions. |
| 6 | - Thrown when invalid domain identifier passed during startSDK() call. - Thrown when there is no internet connectivity during startSDK() call. |
| 9 | Thrown when invalid request URL generated as part of startSDK() call. |
| 11 | Thrown when incorrect request is generated for a request of type GET. |
| 13 | Thrown when a valid response is received for a request, but the status code is not 200. |
| 14 | Thrown when a network request has failed as part of retry of a request (except for time out). |
| 16 | Thrown when the data returned for POST request is nil (empty). |
| 18 | Thrown when maximum retry attempts have been reached. |
| 19 | Thrown when a network request has failed (except for time out). |
| 20 | Thrown when a network request has failed (generic). |
| 22 | Thrown when unable to fetch the original request URL after receiving a response for a POST request. |
| 38 | Invalid response received for the OT SDK network request. Thrown when 1) there is version mismatch between published version and SDK version 2) when incorrect CDN location is used or 3) when app id is wrong or has not been published to. |
| ManagerError | Represents the HeadlessSDK manager related errors in OT SDK. |
| NetworkError | Represents the network layer related errors in OT SDK. |
SDK Initialization
| Message | Log Type | Log Tag | Description | Comments |
|---|---|---|---|---|
| error while fetching OT banner data | Error | NetworkRequestHandler | Logged when SDK cannot give callback to app on Downloading data | This is caused when the OTSDK Callback passed by Application was null. The Application can pass a valid OTCallBack instance on getting the error. |
| network call response error out = + error message | Error | NetworkRequestHandler | Logged when OT SDK data network call failed | |
| empty parameters passed | Warning | OTPublishersHeadlessSDK | Logged when the Application has initialized the SDK with empty parameters. | SDK will throw failure callback and pass error code |
| Invalid language code passed | Warning | OTPublishersHeadlessSDK | This is logged when the Application has initialized SDK with an invalid language code. | Removed from SDK on latest versions, SDK will now return data in default lang configured even if lang code is not passed |
| IAB Vendorlist Api Failed | Error | NetworkRequestHandler | Logged when VendorList API failed while initialising SDK for an IAB Template. | SDK won't be rendering Vendor List UI and encoding vendor values in TCstring if this error is logged. |
| Cannot parse the data received from Server because it is corrupted | Error | OneTrust | Logged when API response is non-empty but does not contain the json required for SDK initialisation/UI rendering | SDK will return failure callback with error code as 7 mainly related to publish issues. Republish and re-download the data in this scenario. |
| Error while parsing Global vendor list | Error | IABHelper | Logged when parsing and saving went wrong with the vendor list data fetched. | This might cause SDK to render blank Vendor list UI or generate corrupted TC string. |
Banner and Preference Center Shown - Reason Codes
Whenever the banner or preference center is surfaced to the user, a reason code will be logged to provide more insight as to why it has surfaced.
This can be useful in a few different use cases:
- Collecting analytics for consent management
- Troubleshooting issues related to surfacing the UI
This can be used to feed any analytics the app is looking to collect such as consents expiring, re-consent triggered, etc.) as well as provide a tool for debugging.
Banner Logging
These codes (except 110) will only work when the banner is surfaced with the setupUI() method.
| Code | Description |
|---|---|
| 101 | Banner shown because 'Show Banner' has been enabled in geolocation rules + user's first time consent + setup() used to surface the banner |
| 102 | Banner shown as re-consent was enabled |
| 103 | Banner shown as consent has expired |
| 104 | Banner shown as TC String has expired |
| 105 | Banner shown as consent has expired (time period set in geolocation rules) |
| 106 | Banner shown because 'service specific' is off (comes down as part of the TC String details). |
| 107 | Banner shown because 100% sync is not complete (for cross device sync setup) |
| 108 | Banner shown because we entered backward compatibility mode and banner has never been shown until now. |
| 109 | Banner shown because region has changed (from non-IAB to IAB region) |
| 110 | Banner shown because the app has called the show banner API. |
Preference Center (PC) Logging
These codes (except 210) will only work when the PC is surfaced with the setupUI() method.
| Code | Description |
|---|---|
| 201 | PC shown because 'Show Banner' has been enabled in geolocation rules + user's first time consent + setupUI() used to surface the PC |
| 202 | PC shown as re-consent was enabled |
| 203 | PC shown as consent has expired |
| 204 | PC shown as TC String has expired |
| 205 | PC shown as consent has expired (time period set in geolocation rules) |
| 206 | PC shown because 'service specific' is off (comes down as part of the TC String details). |
| 207 | PC shown because 100% sync is not complete (for cross device sync setup) |
| 208 | PC shown because we entered backward compatibility mode and banner has never been shown until now. |
| 209 | PC shown because region has changed (from non-IAB to IAB region) |
| 210 | PC shown because the app has called the show PC API. |
SDK Performance
The timer for these performance metrics begins as soon as
startSDK()is called.
