I'm trying to deploy and run a job in docker and getting error about boto library that
I included in docker block but no use in the code yet. what's happening?

```prefect deployment build src/main.py:ingest_everflow -n test-run-container  -q test
-sb s3/s3-everflow/ef_test_code -ib docker-container/de-container -o prefect-docker-deployment --apply```
    `return self.sign(operation_name, request)`
  `File "/usr/local/lib/python3.10/site-packages/botocore/signers.py", line 189, in sign`
    `auth.add_auth(request)`
  `File "/usr/local/lib/python3.10/site-packages/botocore/auth.py", line 418, in add_auth`
    `raise NoCredentialsError()`
*`botocore.exceptions.NoCredentialsError: Unable to locate credentials`*

I believe to use an S3 block your shell needs to be authenticated with AWS / have credentials available in the environment or in ~/.aws/credentials

Prefect will try and upload your deployment to that S3 block, and it will use boto3 to do that, and the error you are getting is boto3 unable to find AWS credentials with which to access S3

<@U04LLKP8KEC> thanks, for some reason the access tokens were gone in sb and now good.
