should assume_role_with_web_identity work even without AWS credentials being found?

[schlichtanders]

I just installed AWS.jl and want to use it for assume_role_with_web_identity. While the equivalent command line version works without complaining, AWS.jl errors:

julia> Sts.assume_role_with_web_identity(role_arn, role_session_name, web_identity_token)
ERROR: Can't find AWS credentials!

assume_role_with_web_identity is indeed special in that it shouldn't need any aws credentials for working.
Is there some workaround to specify nocredentials?

It seems I found a quick workaround by defining an empty AWSConfig. It seems you need to default for some region.

aws_config = AWS.AWSConfig(nothing, "eu-central-1", "json", AWS.AWS_MAX_RETRY_ATTEMPTS)
Sts.assume_role_with_web_identity(role_arn, role_session_name, web_identity_token; aws_config)

I guess this is the intended behaviour. If so, this can be closed
