Google play error when trying to update beta

Question

I'm receiving this error when trying to upload a new apk to my beta channel:

Errors

Resolve these errors before starting the rollout of this release.

You can't rollout this release because it doesn't allow any existing users to upgrade to the newly added APKs.

In my alpha channel, witch is updated far more frequently, I can successfully upload the same apk.

How can I solve it?

Answer 1

I was able to get around this error because I had accidentally set my Version Code to a lower number than the Version Code for an APK in production. Once I increased my version code number to be larger than any previous releases, it worked.
