I'm trying to set my signing credentials in UCB and I'm receiving the error: "Failed to update credentials! Keystore failed validation (invalid password or alias)." However, I am able to use the same release credentials to perform a successful local build. I am also able to use a different debug keystore to successfully build on UCB. The only difference between the 2 is that the debug credentials are in a .keystore file whereas the release credentials are in a .jks file. Are .jks files not supported on UCB?
