If that is really your script then you are looking for a repository with registryId "string" - I doubt that there are any repositories called that. You also want a repository with a blank name, and a previous call has returned a nextToken of "string" - I doubt that too.

When you get scripts from the documentation at ECR — Boto3 Docs 1.16.29 documentation[^] it's a good idea to look at the examples at the bottom of the section, not just the syntax definition.

Try just using the defaults for all of the parameters and build up your script from there - I suggest starting with

import boto3
client = boto3.client('ecr')
response = client.describe_repositories()
