From the console, I am invoking a lambda which submits a batch job. The batch job fails, indicating that ECS is unable to assume the role that is provided to execute the job definition.

For the role, I&#39;ve added the lambda and ECS services.

The error message:

&gt; &quot;ECS was unable to assume the role
&gt; &#39;arn:aws:iam::749340585813:role/golfnow-invoke-write-progress&#39; that
&gt; was provided for this task. Please verify that the role being passed
&gt; has the proper trust relationship and permissions and that your IAM
&gt; user has permissions to pass this role.&quot;

Is the issue with the way it&#39;s being invoked? My user has admin privileges, so I don&#39;t think this is an issue with my user having insufficient permissions.
