Android, Generate Digital Asset Link: keystore file for signing the app

Question

I implemented universal linking for my Android app. Everything works fine so far. I click on a universal link and will be immediately redirected to the app. However, I have always used debug for the Digital Asset Links. For the release I need the signing config or the keystore file.

To sign my app I always use a created xxxx.jks file. If I specify this, an error occurs: Error occured while trying to get the SHA-256 fingerprint (See screenshot).

The error is very meaningless. That's why I'm a little confused. Do I use the right file? How do I get a better error description? I always use this file to sign my app for a new release. That doesn't cause any problems.

I already took the SHA-256 fingerprint from the App signature certificate from the Play Console. This doesn't really work properly. Whenever you click on my universal link, the app asks: Should the link be opened with Chrome or with 'MyApp'?

I am grateful for input.

Okay, the solution was simple. I just take the SHA256 from the google play console. This one you have to put in your assetlinks.json

Then I build a public beta and it works like expected.
