Autodesk.DesignAutomation returning Unexpected token S in JSON at position 0 when calling the workitem api - autodesk-forge

Question

I am facing a new issue with a fetch
handleSendToForge(e) {
e.preventDefault();
let formData = new FormData();
formData.append('data', JSON.stringify({
Width: this.state.Width,
Length: this.state.Length,
Depth: this.state.Depth,
Thickness: this.state.Thickness,
BottomThickness: this.state.BottomThickness,
rebarSpacing: this.state.rebarSpacing,
outputrvt: this.state.outputrvt,
bucketId: this.state.bucketId,
activityId: 'RVTDrainageWebappActivity',
objectId: 'template.rvt'
}));
this.setState({
form: formData
})
fetch('designautomation', {
method: 'POST',
body: formData,
//headers: {
// //'Content-Type': 'application/json'
// 'Content-Type': 'application/x-www-form-urlencoded',
//},
})
.then(response => response.json())
.then(data => { console.log(data) })
.catch(error => console.log(error));
}
and the code for the controller is pretty standard and is slightly modified from one of the forge examples
[HttpPost]
[Route("designautomation")]
public async Task<IActionResult> Test([FromForm] StartWorkitemInput input)
{
JObject workItemData = JObject.Parse(input.data);
double Width = workItemData["Width"].Value<double>();
double Length = workItemData["Length"].Value<double>();
double Depth = workItemData["Depth"].Value<double>();
double Thickness = workItemData["Thickness"].Value<double>();
double BottomThickness = workItemData["BottomThickness"].Value<double>();
double rebarSpacing = workItemData["rebarSpacing"].Value<double>();
string outputrvt = workItemData["outputrvt"].Value<string>();
string activityId = workItemData["activityId"].Value<string>();
string bucketId = workItemData["bucketId"].Value<string>();
string objectId = workItemData["objectId"].Value<string>();
// basic input validation
string activityName = string.Format("{0}.{1}", NickName, activityId);
string bucketKey = bucketId;
string inputFileNameOSS = objectId;
// OAuth token
dynamic oauth = await OAuthController.GetInternalAsync();
// prepare workitem arguments
// 1. input file
dynamic inputJson = new JObject();
inputJson.Width = Width;
inputJson.Length = Length;
inputJson.Depth = Depth;
inputJson.Thickness = Thickness;
inputJson.BottomThickness = BottomThickness;
inputJson.rebarSpacing = rebarSpacing;
inputJson.outputrvt = outputrvt;
XrefTreeArgument inputFileArgument = new XrefTreeArgument()
{
Url = string.Format("https://developer.api.autodesk.com/oss/v2/buckets/aecom-bucket-demo-library/objects/{0}", objectId),
Headers = new Dictionary<string, string>()
{
{ "Authorization", "Bearer " + oauth.access_token }
}
};
// 2. input json
XrefTreeArgument inputJsonArgument = new XrefTreeArgument()
{
Headers = new Dictionary<string, string>()
{
{"Authorization", "Bearer " + oauth.access_token }
},
Url = "data:application/json, " + ((JObject)inputJson).ToString(Formatting.None).Replace("\"", "'")
};
// 3. output file
string outputFileNameOSS = outputrvt;
XrefTreeArgument outputFileArgument = new XrefTreeArgument()
{
Url = string.Format("https://developer.api.autodesk.com/oss/v2/buckets/{0}/objects/{1}", bucketKey, outputFileNameOSS),
Verb = Verb.Put,
Headers = new Dictionary<string, string>()
{
{"Authorization", "Bearer " + oauth.access_token }
}
};
// prepare & submit workitem
// the callback contains the connectionId (used to identify the client) and the outputFileName of this workitem
//string callbackUrl = string.Format("{0}/api/forge/callback/designautomation?id={1}&bucketKey={2}&outputFileName={3}", OAuthController.FORGE_WEBHOOK_URL, browerConnectionId, bucketKey, outputFileNameOSS);
WorkItem workItemSpec = new WorkItem()
{
ActivityId = activityName,
Arguments = new Dictionary<string, IArgument>()
{
{ "rvtFile", inputFileArgument },
{ "jsonFile", inputJsonArgument },
{ "result", outputFileArgument }
///{ "onComplete", new XrefTreeArgument { Verb = Verb.Post, Url = callbackUrl } }
}
};
DesignAutomationClient client = new DesignAutomationClient();
client.Service.Client.BaseAddress = new Uri(#"http://localhost:3000");
WorkItemStatus workItemStatus = await client.CreateWorkItemAsync(workItemSpec);
return Ok();
}
Any idea why is giving me this error? I have tested the api using postman and it works fine but when I try to call that from a button I keep receive this error. Starting the debug it seems that the url is written correctly. Maybe it is a very simple thing that i am missing.
Cheers!

Answer 1

OK solved...
I was missing to add the service in the Startup and also the Forge connection information (clientid, clientsecret) in the appsettings.json
Now I need to test the AWS deployment and I guess I am done!
