Instance Profile creation via the Databricks REST API returns "INVALID_PARAMETER_VALUE"

[lasmali]

# Problem Statement

We have a need to create Instance Profiles via the Databricks REST API, but the endpoint returns an "INVALID_PARAMETER_VALUE" error with "Syntactically invalid AWS instance profile ARN" message even when provided an appropriate ARN as input.

# What's been done

1. Creating Role and Instance Profile on Databricks AWS account via AWS CLI
2. Calling /instance-profiles/add to register Instance Profile in Databricks

# Code

def create_instance_profile(instance_profile_arn, skip_validation = False):
    api_command = '/instance-profiles/add'
    api_version = f'/api/2.0'
    url = f"https://{DATABRICKS_HOST}{api_version}{api_command}"
 
    params = {
      "instance_profile_arn" : instance_profile_arn,
      "skip_validation" : skip_validation,
      "is_meta_instance_profile" : False
    }
 
    header = {
        "accept": "application/scim+json",
        "Authorization": f"Bearer {DATABRICKS_TOKEN}"
    }
 
    response = requests.post(url, params = params, headers=header)
 
    print(json.dumps(json.loads(response.text), indent = 2))
 
arn = "arn:aws:iam::<account_id>:instance-profile/my-instance-profile-name"
create_instance_profile(arn)

Hi, Is this a constant error or intermittent? For newly added profiles AWS has a buffer time and sometimes it is intermittent. Also, could you please provide the full error here along with the screenshot? (Also, you can refer: https://docs.aws.amazon.com/IAM/latest/UserGuide/troubleshoot_iam-ec2.html)

Hi @Debayan Mukherjee​ , I havn't been able to make a successful request via the API (although I'm able to list the instance profiles on our Databricks account via the API), but I can add the instance profile via the Databricks UI without problem.

Here's the response from the Databricks API.
