Changing keystore for android build not working

I had to reset the previous key on Google Play side and now I am trying to set it on my local on expo. However, when I try to upload my own keystore I get this error:
JKS Keystore entry does not contain a certificate, alias: 123456. Run this to find the available aliases: keytool -list -v -keystore [your-keystore-path].

When I run the command the key is there with the alias ‘123456’. Any ideas what’s wrong?
