Docker compose push return 400 unexpected end of JSON input: ""

I have set up the docker registry at DigitalOcean to deploy my django application. I have installed the doctl and setup the API credentials. If I run the command as: doctl auth list i can see my auth as the current one, which has the Read and Write permission. But now, when I try to run the command as:

docker-compose -f docker-compose.staging.yml push

I get the error as:

ERROR: error parsing HTTP 400 response body: unexpected end of JSON
input: ""

Here’s my docker-compose.staging.yml file:
