Did you uncomment the 'DTXLogLevel=debug' in the APK-Instr.properties while instrumenting the application?
# Logging level: "info" (default) or "debug". Note that the logging level is applied to both Auto Instrumentation as well as the instrumented application.
I read somewhere that the debug doesn't work with the CORS because the agent stores the updated configuration in the localstorage of the browser, so you did not inject the debug initcode, therefore, the debug detailed information is not available.
The initialization tag is the same for automatic and manual injection, so before generating 'initcode' through REST API provide the 'Debug agent location' and select 'Log Debug Information' and the place that tag in the index.html as a first script tag in the <head> and try.
I have not set the debug agent path. Do I have to set the debug agent path similar to dynaTraceMonitor path?
(Also, have checked the localstorage in Chrome DevTool, there were o9nly cookies and no debug infos.)
