Why do I get a JsonReaderException with this code?

I've got this code to try to open a .json file and read it:

C#

[Route("{unit}/{begindate}")]
public string Get(string unit, string begindate)
{
    string _unit = unit;
    string _begindate = String.Format("{0}01", PlatypusWebReportsConstsAndUtils.HyphenizeYYYYMM(begindate));
    string appDataFolder = HttpContext.Current.Server.MapPath("~/App_Data/");
    // semi-hardcoded file name for now
    string jsonFilename = string.Format("PoisonToe_{0}_{1}.json", _unit, _begindate);
    string fullPath = Path.Combine(appDataFolder, jsonFilename);
    JObject platypusComplianceJson = JObject.Parse(File.ReadAllText(fullPath));
    . . .

On the last line, I get:

Newtonsoft.Json.JsonReaderException was unhandled by user code
HResult=-2146233088
Message=Error reading JObject from JsonReader. Current JsonReader item is not an object:

Based on what I read here, I thought this would be the way to do it. What am I doing wrong?

Is it an array? :-)

Is what an array? The .json file?

Have you checked that the return value from File.ReadAllText(fullPath) actually contains data.
That's the only thing I can see that could go wrong.

It's the same path I used to save the file in the first place, and is there, and has content, so...

As I said, that was the only thing I could think of.
I just tried the code on a very simple JSON file and it works fine.
You probably have an error in the file you are reading.
Try something simple like:
{
"Hello":"World"
}
