DWG to GeoJson Convert giving "400 Bad Request [No Body]" error intermittently

DWG to GeoJson Convert giving "400 Bad Request [No Body]" error intermittently

notescrew 51

I am using Azure Maps API for DWG to GeoJson conversion. I works fine, but on some days intermittently I am getting 400 Bad Request [no body] error.

And once it's received it stays for more than a day and I am not able to do any conversion during that time. Even it stops working for the DWG files those used to work previousely.

Here are my logs:

While the same code and same DWG files start getting processed after some days.

Hi @notescrew

When you say you aren't able to any conversion during that time

What kind of response are you getting?

How many other conversions are running but not finished?

When you get the " Failed async method processing :" response, is that happening with your POST request or the GET request to get the status? If it is the GET request, could you provide the GET method URL that contains the operation Id?

Hi @Brendan Co ,

Thanks for your reply.

What kind of response are you getting?
Answer :

I upload the zip file containing DWG is uploaded successfully. with below endpoint
https://eu.atlas.microsoft.com/mapData?&api-version=2.0&dataFormat=dwgzippackage&subscription-key=********************** : POST Method

After that I checked the upload status with below endpoint. And it returned successful.
https://eu.atlas.microsoft.com/mapData/operations/d2cd52c1-d8b8-429f-8a77-5f2dd7e6d6b6?api-version=2.0&subscription-key=********************** : GET Method

After that I call below endpoint to convert it to GeoJson. And that is failing with status 400 Bad Request: [no body]
https://eu.atlas.microsoft.com/conversions?subscription-key=**********************&api-version=2.0&udid=a5e0bdf2-641e-a044-c954-d44f2d27b9a2&inputType=DWG&outputOntology=facility-2.0 : POST Method

(mode details like headers and body responses are in original question)

How many other conversions are running but not finished?
Answer:
I think there was one conversion going on, for which it neither gave failed nor successful. But not sure if it is still running or not. How I can check the current running conversion? Doesn't Maps API allows multiple conversion parallelly? How I can kill that long running conversion?

When you get the " Failed async method processing :" it is for the POST endpoint https://eu.atlas.microsoft.com/conversions?subscription-key=**********************&api-version=2.0&udid=a5e0bdf2-641e-a044-c954-d44f2d27b9a2&inputType=DWG&outputOntology=facility-2.0 .

Hi @notescrew ,

Thanks for the information. The LIST APIs will only show successfully completed operations, so if something is still running, you will need to log the operation Id to check on the status. Multiple conversions are allowed to run in parallel, however I believe there is currently a limit of 3 parallel conversions. There isn't a way to cancel a running operation at this time. Async calls that are throttled are currently return a 400 with no body (a bug), so I suspect that you may be experiencing that.

Conversion operations complete relatively quickly (within a few minutes at most), so if you are seeing ones that don't complete please share the operation Ids of the conversions that don't complete.

We will also continue investigating this on our end, however due to holidays, there may be a delay in response.

Thanks

Hello @Brendan Co ,

Thanks for your response. As I have just started exploring it, I don't have that running operationId with me (sorry for that). But I can share the DWG file and details for that, which make it to execute for more than 10 minutes (that's minimum even more than that in most cases).

Specifically for DWG files downloaded from https://knowledge.autodesk.com/support/autocad/downloads/caas/downloads/content/autocad-sample-files.html (visualization sections) has only one layer 0. So when I add 0 as unit and exterior layer names. It hangs and after that for other DWGs also, it stop giving response (error 400 [no body]). So looks like it's halting after 3 such files as max limit is 3.

If there is no way to stop running process, then what could be the reason for such long running processes of conversion? It will prevent other DWG processing in my application.

Request you to please help with this on priority as it blocks (already blocked) everything for me. And I am waiting since yesterday to work it again.

Hi @notescrew ,

We took a look at the sample packages that you are referring to and it looks like it is 3D data which is not supported by Creator. Drawing requirements are specified here. Here is a tutorial which includes a sample package that is compliant. The conversion service should be aborting sooner with this unsupported package and we are still continuing that investigation.

Hello @notescrew ,

I'm one of the engineers on the team looking into why you were not able to continue submitting requests for 4-6 hours after being throttled. To help me reproduce the issue on my side, can you share with me your manifest and/or the zip package(s) that you uploaded?

Thank you in advance,
Nikki

Ok, thanks for update. But I believe that it should not throttle the process for hours. Rather it should immediately fail it, with proper error message in response. I will share my Zip package for testing at your side.

Sorry for delayed response, I missed this comment.
