retrofit2.HttpException: HTTP 401

[658jjh]

I got one issue reported by Crashlytic.

Fatal Exception: retrofit2.HttpException: HTTP 401 
       at retrofit2.KotlinExtensions$await$2$2.onResponse(KotlinExtensions.kt:53)
       at retrofit2.OkHttpCall$1.onResponse(OkHttpCall.java:161)
       at okhttp3.internal.connection.RealCall$AsyncCall.run(RealCall.kt:519)
       at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167)
       at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
       at java.lang.Thread.run(Thread.java:923)

I handled the regular 401 code in an Intercepter, so I don't know how it could happen.
Does anyone know why and how to prevent that from happening again?

My team is also struggling to address this error.

Hi, do any of you found a workaround for this issue ?

[byates-fleetian]

We eventually solved this by auditing our error handling for calls made inside a coroutine. It appears that retrofit errors tend to be swallowed by the coroutine unless handled explicitly.

Can you tell me how you implemented this?

[byates-fleetian]

We made a wrapper which executed our retrofit calls inside a coroutine with the relevant try catches surrounding it. And then we made sure all HTTP calls were using the wrapper.
