Wrong value generated by CfnAssociation.parameters, should interpret the ParameterValuesProperty list of string only for CF to accept it

[chefren]

❓ General Issue

The Question

aws-ssm.CfnAssociation expects a CfnAssociation.ParameterValuesProperty, but upon deployment, CF expects a list of string

Environment

• CDK CLI Version:1.18.0 (build bc924bc)
• Module Version:1.18.0
• OS:all
• Language:Python

Other information

First reported on SO

CF error:

Value of {Parameters} must be a map where each value is a list of {String}

[chefren]

CDK generates what appears to match the CF doc type definition:

    "Parameters": {
      "Directory": {
        "ParameterValues": [
          "myWorkSpace"
        ]
      }
    }

The same CF doc example actually shows a map of key:value, where the value is a list of strings. Which is also what is shown in the syntax initial section, and what the CF console appears to accept, according to the error.

    "Parameters": {
      "Directory": ["myWorkSpace"]
    },
