oci compute compute-capacity-report says invalid json with generated sample json

oci compute compute-capacity-report reports Parameter 'shape_availabilities' must be in JSON format. when using example json.

Following the documentation here ...
https://docs.oracle.com/en-us/iaas/tools/oci-cli/3.37.7/oci_cli_docs/cmdref/compute/compute-capacity-report/create.html

oci compute compute-capacity-report create \
--generate-param-json-input shape-availabilities > shape-availabilities.json  

shape-availabilities.json

[
  {
    "faultDomain": "string",
    "instanceShape": "string",
    "instanceShapeConfig": {
      "memoryInGBs": 0.0,
      "nvmes": 0,
      "ocpus": 0.0
    }
  },
  {
    "faultDomain": "string",
    "instanceShape": "string",
    "instanceShapeConfig": {
      "memoryInGBs": 0.0,
      "nvmes": 0,
      "ocpus": 0.0
    }
  }
]

Running

 oci compute compute-capacity-report create --availability-domain $availability_domain \
--compartment-id $compartment_id --shape-availabilities file://shape-availabilities.json

Results in

Parameter 'shape_availabilities' must be in JSON format.
For help with formatting JSON input see our documentation here: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#ManagingCLIInputandOutput

I followed the examples here https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/cliusing.htm#ManagingCLIInputandOutput but cant seem to make any sense of it.

I suspect there is a bug with the way the report expects input or how the sample data is generated? Thanks in advance.

Start with the compute compute-capacity-report create command and its --generate-param-json-input shape-availabilities output. Reproduce the reported validation error with the documented JSON, then trace how the generated sample is parsed; done means the documented sample is accepted or the documentation clearly matches the required input.
