Parsing error due to invalid body ASK CLI

Using ASK CLI, I'm trying to update my smart home skill manifest but I'm facing the below error.

ask smapi get-skill-manifest -s amzn1.ask.skill.6d0d22eb-d305-4caa-8921-503cb7827454 -p supreet > skill-manifest.json

I have just changed a spelling in the downloaded manifest.

ask smapi update-skill-manifest -s --manifest $(cat skill-manifest.json)

OR

ask smapi update-skill-manifest -s --manifest skill-manifest.json

"response": {
      "message": "Request is not valid.",
      "violations": [
        {
          "code": "INVALID_REQUEST_PARAMETER",
          "message": "Parsing error due to invalid body.",
          "validationDetails": {
            "originalInstance": {
              "type": "BODY"
            },
            "reason": {
              "type": "MALFORMED_INPUT"
            }
          }
        }
      ]
    }

Here's the skill-manifest.json

    },

        }
      },

    }
  }
}

I ran into the same issue few months ago while uploading a manifest. The issue was that the json file had to be preceded by the prefix "file:" like:

--manifest "file:manifestFile.json"

And so your command would be:

ask smapi update-skill-manifest -s --manifest "file:skill-manifest.json"

Here are more details about this.
