Credentials.__new__() takes 5 positional arguments but 6 were given

[philippkeller]

• I installed aws-export-credentials with pipx
• which aws-export-credentials -> /Users/philipp/.local/bin/aws-export-credentials

If I start aws-export-credentials without any params I get error

Credentials.__new__() takes 5 positional arguments but 6 were given

Any advice?

+1 Seeing this as well

This tool is no longer maintained, because there's native support for it in the AWS CLI: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/configure/export-credentials.html
That said, I'll take a look at what changed in botocore

[benkehoe]

What's the output when you run with --debug?

@benkehoe I did not debug it yet just saw this error today also

DEBUG:botocore.credentials:Retrieved credentials will expire at: 2025-04-15 19:43:30+00:00

Was facing this issue, made a temporary fix by downgrading boto3 for aws-export-credentials

pipx inject aws-export-credentials boto3==1.28.57

[alexshenia]

@pranav-md u can use 1.36.26

[avoidik]

while export-credentials.html has been introduced to aws cli, it doesn't support export to a credentials file (AWS_SHARED_CREDENTIALS_FILE)

[uhinze]

Full command to run nowadays (with ux): uvx --with "boto3==1.36.26" aws-export-credentials
