Azure Content Understanding is not returning any response back

Question

Azure Content Understanding is not returning any response back

Mamillapalli, Vamsi Dhar 30

I am using Azure Content Understanding which is in preview. I am trying to extract document contents for my analyzer. Somehow today, I am unable to get any response back from Azure Content understanding. All my requests keeps on running.
Is there a way to know why my requests are taking long time?
Are there any API to view existing requests and if there is any hold up?

And most importantly, how we know why our document is taking long time for analysis?

Hello Mamillapalli, Vamsi Dhar,

Thank you for posting on Microsoft Learn Q&A.

If your requests to Azure Content Understanding are taking a long time, remember that the service works asynchronously, so processing time depends on the size and complexity of your document and current service load.

You can check the status of any request using the request-id from your POST call. A GET request with this id will show if it’s Running, NotStarted, or Succeeded. This helps track progress even if responses are delayed.

There isn’t an API to view all requests at once, but enabling diagnostic logging on your resource can help identify delays or patterns. Large documents, complex content, or high service load are common reasons for longer processing times.

Monitoring logs and the request status gives you a better idea of why some documents take longer and helps manage your analysis efficiently.

Thanks for your reply. There is some thing else going on here. Even the examples which are in try-it-out section are failing. Above screenshot clearly saying service is unavailable. I know this feature is in preview. Just curious know is really service unavailable or there is something else going on from my side. I have no way to track this. Hence I reached out. All this started around 10:30 AM EST.

I enabled tracing in Azure foundry. But I am not seeing any requests from Azure Content understanding. Can you guide me on how to Monitor logs for Azure Content understanding requests?

Having the SAME issue!!! This is crazy, I was just about to launch into production and this would have killed me. Trying Twitter (X) for help but right now I've let it time out after 20 minutes without a response on a 1 page 64kb document that usually comes back in 15 seconds.

Wow we did the same troubleshooting. I tried different analyzers and also their public "Try it now" and it just sits there... There's definitely a service issue they need to take a look at.

Good morning, in my case, the problem has persisted for two days now: either the analyses are left waiting indefinitely, or it takes too long to generate the field extraction, even if what is requested is to extract the fields from a single-page document.

The issue has been resolved from my side after couple of days. Thanks for your support.

I have run into exact same problem today. Content understanding was working on Friday October 31st, but today Nov 3 it's no longer working. I can successfully make post request for document analysis, but the analysis is stuck forever, polling just shows status Running.

The try it out option in Azure AI Foundry console, also gets stuck analyzing their own sample document. How did you end up resolving your issue? Did you just wait it out?

I am wondering if this issue happens often, in which case wondering if it's worth using Content Understanding on production. Or better switch to FormAnalyzer, which might be more consistent.

Hi! We experience the same issues. We started trying out content understanding. After labelling about 15 documents (2-4 pages each) the analysis stopped working.

It does not matter if we use "test analyzer" of if we use "labelling", uploading new files does not help either...

Looks like some queue is "stuck" for our account.

I'm experiencing the same problem. After several documents went through fine, now requesting a single page has been "running" for several hours

I went back to Document Intelligence. CU is still not ready for prod use, and far lower throughput
