getURLContentAsync throwing exception on non-200 success response [#16757]

Hi,
I have a local webservice. If the webservice is queried via get request and doesn't have any content for the request, it responds with http 204 - No Content (and no content). For reference, if I'm using invoke-webrequest to access the service, I get this:

Code: Select all

Invoke-WebRequest -Uri $url

StatusCode        : 204
StatusDescription : NoContent
Content           : {}
RawContent        : HTTP/1.1 204 NoContent
                    Date: Sat, 27 Jun 2020 08:21:37 GMT
                    Server: Kestrel
                    Content-Length: 0

Headers           : {[Date, System.String[]], [Server, System.String[]], [Content-Length, System.String[]]}
RawContentLength  : 0
RelationLink      : {}
I'm not sure if this is intentional or not, but it seems like getURLContentAsync doesn't handle this all too well. I'm using the code below:

Code: Select all

let headers = newStringList();
headers.add('Content-Type: application/json');

try {
  let response = await app.utils.web.getURLContentAsync(requestUrl, {
	headers: headers
  });
  let parsedResponse = JSON.parse(response);
} catch (error) {
  console.log('Error: ' + error.response)
}
The output I get from running this
Error: Access violation at address 0133566A in module 'MediaMonkeyEngine.exe'. Read of address 00000000

I was also able to reproduce this by using promises instead of async with some code I borrowed from lyricsSearch.js:

Code: Select all

var downloadPromise = app.utils.web.getURLContentAsync(requestUrl, {
  headers: headers
});
downloadPromise.then(function (Content) {
  console.log('succeeded ' + Content.response)
}, function (Content) {
  console.log('failed ' + Content.response)
}).catch(err => {
  console.log('err ' + err)
});

And the output I get:
failed Access violation at address 0133566A in module 'MediaMonkeyEngine.exe'. Read of address 00000000
Is there another way to handle these kind of requests, or is this intended behavior?

Thanks for reporting, I can replicate using:

Code: Select all

app.utils.web.getURLContentAsync('https://httpstat.us/204');
