Unsupported Argument - 'An argument named "ARN" is not expected here.' in 'dome9_cloudaccount_aws'

[paul-ej]

When attempting to onboard an AWS account using the dome9 terraform provider, when running 'terraform plan', no issues shown, but when running 'terraform apply', prompts with an error that ARN is not supported within the credentials block within the 'dome9_cloudaccount_aws'.

Terraform versions tested:
1.2.0
1.2.2

Provider versions tested:
1.26.0
1.25.4

What was your error message looked like? I also had similar error when onboarding. Even I tested with cli 'aws sts assume-role --role-arn xxx ...' that showed my arn and external id and trust role all good.

I need to see the Terraform resource configuration in order to help you
