Bitbucket doesn't read my base64 encoded json file with Google cloud service key.
I have successfully encoded and then decoded the same file myself, that Bitbucket tries to decode.
But Bitbucket fails to do it with base64: invalid input error.
Here is the full error message:
Status: Downloaded newer image for bitbucketpipelines/google-app-engine-deploy:0.6.1
INFO: Setting up environment.
echo "${KEY_FILE}" | base64 -d >> /tmp/key-file.json

As I understand it fails here, on "project_id": ".
Decoded file looks like this:
{
"type": "service_account",
"project_id": "project-318",
"private_key_id": "...",
...
}
I have tried to feed my base64 encoded key file firstly through environment variable and then through file. But with the same error. When it cannot extract JSON bitbucket writes this error:
ERROR: (gcloud.auth.activate-service-account) Could not read json file /tmp/key-file.json: No JSON object could be decoded
Turns out that the key file from google cloud contains newline symbols: \n.
So result base64 encoded file also looked like this:

.....
But in order to pass it to Bitbucket you need to have it all in one line:

After I manually removed new line symbols it gave success message:
