Error: Cannot find changelog because no version code given - please specify :version_code

Hi,
Im new to fastlane and Im facing the error in the topic from my app. uvc_camera.
I installed fastlane using this guide.
First I executed fastlane supply init in my project folder. This worked successfully and I got all the metadata in my fastlane folder.
When I try to run fastlane supply I get the following error:
fastlane supply errer.txt

The output of fastlane env is the following:
fastlane env.txt

The app is a Android Studio Project. In particular fastlane should take the versionCode number of the apps build.gradle file to set its actual version_code. When I run the command fastlane supply --aab app/release/app-release.aab --track beta --rollout 1` then fastlane is able to read the version code out of the aab file, which I have created with android studio. Fastlane is then able to push the app to Google Play Store.

Can anyone give me the right procedure to execute the fastlane supply command without getting this error.
Thx in advance, Peter
