Stub response fails with unexpected parameters

[viraptor]

Describe the bug

When trying to test ECS code, the following code fails unexpectedly:

new_task_definition = client.stub_responses(:register_task_definition, task_definition: { task_definition_arn: 'arn:aws:ecs:us-east-1:123456789012:task-definition/23456789012' })
client.stub_responses(:register_task_definition, new_task_definition)

The error is:

     Failure/Error: client.stub_responses(:register_task_definition, new_task_definition)
     
     ArgumentError:
       parameter validator found 2 errors:
         - unexpected value at params[:http]
         - unexpected value at params[:mutex]

Even though http and mutex parameters are not present anywhere in my code.

Reproduction Steps

require 'aws-sdk-ecs'
client = Aws::ECS::Client.new(stub_responses: true)
new_task_definition = client.stub_responses(:register_task_definition, task_definition: { task_definition_arn: 'arn:aws:ecs:us-east-1:123456789012:task-definition/23456789012' })
client.stub_responses(:register_task_definition, new_task_definition)

Possible Solution

No response

Additional Information/Context

No response

Gem name ('aws-sdk', 'aws-sdk-resources' or service gems like 'aws-sdk-s3') and its version

Unset the potential regression. I checked versions 1.100, 1.50, 1.25, 1.0 and they're all failing the same way.

Thanks for opening an issue. This appears to be an issue with usage. You should only need to call stub_responses once. The following will work

require 'aws-sdk-ecs'
client = Aws::ECS::Client.new(stub_responses: true)
client.stub_responses(:register_task_definition, task_definition: { task_definition_arn: 'arn:aws:ecs:us-east-1:123456789012:task-definition/23456789012' })

# fill these out
client.register_task_definition(family: ..., container_definitions: ...)

Yeah, that's one place that I used stub_response rather than stub_data by copy/paste accident 🤦
