RisingWave Community - Why does S3 fail to find a file in a subfolder under the bucket for Protobuf parsing?

When specifying the schema.location for Protobuf parsing in S3, the path should include the full path to the file, including the folder structure.
S3 may have issues parsing the / in the path if not properly formatted.
Ensure that the path to the file in the subfolder is correctly specified in the S3 descriptor file.

Example:

FORMAT PLAIN ENCODE PROTOBUF (
    message = 'ProtoClass',
    schema.location = '<s3://my-bucket/protobuf/descriptorset.pb>',
    access_key ='...', secret_key='...', region='...'
);```
