Android signing is not working

Bug description

When I add androidKeystoreName, It seems that the android build is not using that and use some other keys for signing (The custom key store is not ticked in unity editor as the document said)

Error after uploading to google play :

[!] Google Api Error: forbidden: The Android App Bundle was signed with the wrong key. Found: SHA1: 
22:59:3D:65:70:BB:95:44:31:BB:F2:F4:7F:29:B4:4B:B4:60:5C:5A, expected: SHA1: 
E9:61:CD:E5:51:BF:84:CE:D0:2B:64:B3:36:CE:EE:B0:46:78:D6:64. - The Android App Bundle was signed with the wrong key. Found:

E9:61:CD:E5:51:BF:84:CE:D0:2B:64:B3:36:CE:EE:B0:46:78:D6:64.

I even add some wrong base64 input to see what will happen and here is some part of the logs :

2021-02-02T20:24:06.3590246Z -rw-r--r-- 1 root root   86 Feb  2 20:24 VersionGenerator.cs.meta

2021-02-02T20:24:06.3597502Z Using custom parameters .

But even with that error, the project successfully builds with no signing error.

This is my github action:

@dopaminegamesstudio The docs are wrong. I’ll fix. Thanks for bringing this up!

Are you using Google Play signing? If so, are you using the Upload key certificate and NOT the App signing key certificate? Does running keytool -list -v -keystore $androidKeystoreName -alias $androidKeyaliasName match what you see for the Upload key certificate in Google Play?
