  • 1.  Trouble accessing async object from RestAPI Prefer: respond-async

    Hi all,

    I'm having trouble interacting with the TM1 rest API in the following way. I'm hoping maybe there's some obvious that I'm missing :)

    Kick-off TI process

    public async static Task<string> RunProcessWithPolingAsync(TM1SharpConfig tm1, string processName, Dictionary<string, string>? parameters = null)
{
	var client = tm1.GetTM1RestClient();

	client.DefaultRequestHeaders.Add("Prefer", "respond-async");

	var jsonBody = new StringBuilder();

	if (parameters != null)
	{
		jsonBody.Append("{\"Parameters\":[");

		parameters.AsEnumerable().ToList().ForEach(x =>
		{
			jsonBody.Append("{\"Name\":\"" + x.Key + "\", \"Value\":\"" + x.Value + "\"}");
		});

		jsonBody.Append("]}");
	}

	var jsonPayload = new StringContent(jsonBody.ToString(), new MediaTypeWithQualityHeaderValue("application/json"));

	var response = await client.PostAsync(tm1.ServerHTTPSAddress + @"/api/v1/Processes('" + processName + "')/tm1.ExecuteWithReturn", jsonPayload);

	var asyncId = ParseAsyncId(response.Headers.Where(x => x.Key.Equals("Location")).First().Value.First());

	return await GetAsyncStatus(tm1, asyncId);
}

    Returns location header, parse out ID: 

    ../_async('OLTJUN4E4XFBAoV1fiSrQsmK9tn1U')

    Call to check status always 404s. Doesn't matter how long I wait or how many times I check.

    https://server:port/api/v1/_async('OLTJUN4E4XFBAoV1fiSrQsmK9tn1U')
Status Code: 404
Content: {"error":{"code":"278","message":"Resource '/api/v1/_async('OLTJUN4E4XFBAoV1fiSrQsmK9tn1U')' not found"}}

    Reference: https://community.ibm.com/community/user/businessanalytics/discussion/executewithreturn-asynchronously

    User Robert Gordy advised that he was able to resolve the issue with 404 / not found, but I don't see specific steps taken :(

    Solution: Make sure you're attempting to access the async object / endpoint from the same http session that you started the TI process on. Trying to access it from a different http session will always 404.

    Hi, Nick

    Thanks for follow-up. One thing I want to confirm, does it have to be the same HTTP session to do query this async id? Is it possible across sessions?

    async jobs are session scope, so 'yes' as as generalization.

    glancing at the code reference, did not see the response cookies get stored for reuse into subsequent calls, so that seems like the likely thing to change.
