Can you please check the below troubleshooting guide :
Credentials configuration error messages:
Malformed request: Failed credential configuration validation checks
The list of permissions checks in the error message indicate the likely cause of your problems.
- If the credential configuration validation fails fewer than ten permission checks, it’s likely that your IAM policy is missing those specific permissions. Copy the correct policy from the article Create a cross-account IAM role.
- If the credential configuration validation fails ten or more checks, it’s more likely that the trust relationship of the IAM role is incorrectly set up. Verify that the trust relationship of your customer role is set up properly according to instructions in the article Create a cross-account IAM role.
If both your policy and trust relationship appear to be correct, also check the following:
- Confirm that you include the correct role ARN in the credentials object.
- Confirm whether you have organization-level service control policies (SCPs) that deny the
- AssumeRole
- action or deny EC2/VPC access. If you are unsure, ask your AWS administrator about SCPs.
