Passing parameters to the Glue Workflow using Python

Question

I'm trying to run a Glue Workflow from the lambda. According to [this documentation](https://docs.aws.amazon.com/glue/latest/dg/aws-glue-api-workflow.html#aws-glue-api-workflow-StartWorkflowRun) there is a parameter `RunProperties`. So, I'm trying to run the workflow like this:
```
newRun = glue.start_workflow_run(Name = 'MyWorkflow', RunProperties = { 'key1': 'value1' })
```
But getting the error:
```
[ERROR] ParamValidationError: Parameter validation failed:
Unknown parameter in input: "RunProperties", must be one of: Name
```
It looks like it waits only one parameter `Name` but not `RunProperties`.
The question is: How can I run my workflow with parameters from a lambda function?

Some additional information:  
What I'm trying to achieve here is to run a Glue Workflow when a zip file uploaded to S3. I don't want to run a crawler because it's redundant here. When a zip file is uploaded to S3, a lambda is started and from it I want to start the Glue Workflow.

Hi, @Alex

I tried and encountered the same problem as you.

As a workaround, you can put the parameters immediately after using the RunId of the workflow started without properties.

```
newRun = glue.start_workflow_run(Name = 'MyWorkflow')
updateRun = glue.put_workflow_run_properties(
    Name = 'MyWorkflow',
    RunId = newRun['RunId'],
    RunProperties = { 'key1': 'value1'}
    )
```

Maybe this is a boto3 issue.   
I think I can report this issue...
