Google Play error trying to update beta

Question

I get this error when trying to upload a new apk to my beta channel:

Mistakes

Correct these errors before deploying this version.

You cannot deploy this version because it does not allow new users to upgrade to new APKs.

In my alpha channel, the witch is updated much more often, I can successfully download the same apk.

How can I solve it?

Answer 1

I managed to get around this error because I accidentally set my version code to a smaller number than the version code for the APK in production. As soon as I increased my version code to more than all previous releases, it worked.
