Awsume error: Validation Exception - Invalid credentials returned from credential_process:

[alexiskat]

My setup seems to be hitting this exception for some reason.

my ~/.aws/config file is:

[profile ak-ssodev]
sso_start_url = https://d-XXXXXXX.awsapps.com/start
sso_region = eu-west-1
sso_account_id = 1234567890
sso_role_name = Administrator
region = eu-west-1
output = json
credential_process = aws-sso-util credential-process --profile ak-ssodev

If I run aws-sso-util credential-process --profile ak-ssodev that works fine. I get the following json
{"Version":1,"AccessKeyId":"XXXXXXX","SecretAccessKey":"XXXXXXX","SessionToken":"XXXXXXX","Expiration":"2022-09-23T15:09:58Z"}

but if I run awsume --debug ak-ssodev then i get the following:

Using

awsume -v
4.5.3

with

aws-sso-util --version
4.29.0

thanks for any advice

@alexiskat did you ever figure out what was wrong? I'm running into the same issue now.

[alexiskat]

@lagerfeuer Sorry, I never did and ended up switching to https://github.com/synfinatic/aws-sso-cli

[lagerfeuer]

@alexiskat I figured, I switched to aws-vault. Thanks for the prompt response!
