Hey LuckyKangaroo60
So far there isnt a CLI command to check the conf file format : if there is an error, it is detected from the beginning of the execution and the program fails. Here is what i use as a conf for accessing my local docker based minio :

`
s3 {
# S3 credentials, used for read/write access by various SDK elements

        # Default, used for any bucket not specified below
        region: ""
        # Specify explicit keys
        key: "david"
        secret: "supersecret"
        # Or enable credentials chain to let Boto3 pick the right credentials. 
        # This includes picking credentials from environment variables, 
        # credential file and IAM role using metadata service. 
        # Refer to the latest Boto3 docs
        use_credentials_chain: false

        credentials: [
            # specifies key/secret credentials to use when handling s3 urls (read or write)
            # {
            #     bucket: "my-bucket-name"
            #     key: "my-access-key"
            #     secret: "my-secret-key"
            # },
            {
                 # This will apply to all buckets in this host (unless key/value is specifically provided for a given bucket)
                 host: "localhost:9000"
                 key: "david"
                 secret: "supersecret"
                 multipart: false
                 secure: false
             }
        ]
    } `ps. please blur your credentials  🙂

thanks I am gonna check that.

PS : it's a toyset credential, thanks 🙂

i guess it is... but still 😉

it's working thanks, it was due to 1) the Boto3 library which was not installed 2) the fact that I was working in a jupyter notebook & the clearML file was not reloaded (I think?)
