Gonna update to 7.1.0 and see if that helps

edenman on 23 Nov 2020

This has now happened four times, all to the same user. Who of course, I can't communicate with because presumably they haven't successfully logged in yet.

And I can't update to 7.1.0 because of #1874, waiting for 7.1.1.

edenman on 25 Nov 2020

I'm happy to submit a PR for this, just let me know what approach you'd like to take:
1) Catch the ANFE in the FlowUtils.startIntentSenderForResult methods
2) Check for null Intent in FlowUtils.unhandled and no-op
3) Perform some initial validation on the PendingIntent to ensure it's valid? Not sure what this would look like
4) Something else?

edenman on 25 Nov 2020

@edenman sorry for my slow response and thanks for the offer of a PR. Before we try to add a fix to catch this error I'd really like to find a way to reproduce it. Otherwise it could be covering up something larger.

samtstern on 1 Dec 2020

Gotcha. How about a half-measure: catch the exception, add some more information about how we got in this state, then re-throw? I can't actually tell if you're able to grab that information early enough, though.

edenman on 1 Dec 2020

@edenman sorry for the slow response, I'd be fine with that!

Also 7.1.1 is out now, let me know if that fixes #1874 for you. I haven't had anyone confirm that directly yet.

I poked around and I can't even figure out what could be causing this so I don't know what/where to add logging. Lmk if you have guidance or if you can just add it yourself?

edenman on 6 Dec 2020

No worries I'll look into this one!

Hi! A few weeks ago I was able to reproduce that same error with another app I installed. @edenman , if you want me to try yours and see if I can reproduce it, just drop me a line.

This is still happening in 7.1.1

edenman on 17 Dec 2020

This is happening for my app, too:
