Unable to use 'service-role/xxx' when calling `createActivation`

Question

I use aws-sdk-js to create activation, here is the code:

```
const AWS = require('aws-sdk');
const ssm = getSSM({ region: 'us-east-1' });
ssm.createActivation({
  IamRole: 'service-role/AmazonEC2RunCommandRoleForManagedInstances'
}, (...args) => console.log(args));
```

And I got the following error:

```
{ ValidationException: 1 validation error detected: Value 'service-role/AmazonEC2RunCommandRoleForManagedInstances' at 'iamRole' failed to satisfy constraint: Member must satisfy regular expression pattern: ^[\p{L}\p{N}+=,.@\-_]*$

```

I created an issue at aws-sdk-js repo: https://github.com/aws/aws-sdk-js/issues/2748 , and I was told that the regex validation error comes from the server side.  
  
Based on the reference of AWS SSM API, there is no regex pattern constraint on the IamRole parameter. (https://docs.aws.amazon.com/systems-manager/latest/APIReference/API_CreateActivation.html) Why does the server returns a regex error?

Answer

Thank you for the update!

Answer

Glad to help! I believe this issue should be resolved by now.

Answer

Hi there, this is a known bug recently introduced in our validation, and a fix is rolling out (should be relatively fast, but I can't guarantee any specific timeline).   
  
In the meantime, to unblock yourself, you can use the steps outlined here https://docs.aws.amazon.com/systems-manager/latest/userguide/sysman-service-role.html in order to create a role that doesn't contain the problematic 'service-role/' portion.
