Please check your Project Diagnostics tab. It can be found within the "Build and Upload" section of the Playable Plugin.
This is where you can find all project errors, warnings and suggestions displayed in an easy-to-navigate and categorised way.
This works together with Playable Health Check (PHC) which will point out your project health status and what can be improved.
If your playable includes a script that makes use of an API we do not support, in this case you can make use of our Scripting Defines to preprocess any lines that call upon this API.
Or if this API is being used throughout a script, and this script is not necessary for your playable to work, you can exclude the whole script using our Code Excludes tab.
You can read further about compilation errors and how to fix them here.
