JSON expecting value ','

Question

I'm working on a vCenter upgrade via CLI, and am using the JSON templates provided by VMWare to prep the upgrade. Running the pre check validation, the it throws this error:

Error: Quotation mark parsing error.
Cause: A '}', or ']', or ':', or ',' could be missing between line 22 (character
1) and line 23 (character 19), or quotation marks ('"') may not be properly
escaped.

Here's the template in its entirety:

    "__comments": "Sample template to upgrade a vCenter Server Appliance 6.7 with an embedded Platform Services Controller to a vCenter Server Appliance 7.0 with an embedded Platform Services Controller on a vCenter Server instance.",

    }
}

I've tried adding a comma after "COLO Prod Cluster" as well as various other permutations with and without delimiters. The reading I've done so far hasn't been especially helpful unfortunately, though I suspect it's something simple that's eluding me. Any help is greatly appreciated.

Answer 1

you have only one invalid place of your json,

  "target": [
                "COLO Servers"
                "COLO Prod Cluster",
            ]

should be

    "target": [
                "COLO Servers",
                "COLO Prod Cluster"
            ]
