Logic App - Response timeout issue

Question

Logic App - Response timeout issue

Vivek Komarla Bhaskar 956

Hi,

The logic app communicates with the API management service and retrieves information from the Synapse database.

I sometimes get Response timeout errors for some reason. How can I increase the timeout value so that I can avoid this issue from occurring in the future?

Hi Vivek, thanks for reaching out! I'm happy to help. I see your logic app isn't running that long, so an actual timeout would be a bit strange. Assuming that the time between actions isn't long either.

From what point are you calling this logic app? Is it possible to show me that? So basically I mean two things:

I remember from our earlier contact that you've got an APIM in front, can you show me the policy?

Do you have different callers working with the APIM?

If so, is it always happening with the same caller? Could it be their application isn't waiting for the response?

Hi Sonny,

Basically, things have remained the same from our last conversation, I only have one client on the APIM and below is the policy. It doesn't happen often, but it happens occasionally and when it happens the client receives a null response.

<policies>
    <inbound>
        <base />
        <set-method id="apim-generated-policy">POST</set-method>

        <set-header id="apim-generated-policy" name="Ocp-Apim-Subscription-Key" exists-action="delete" />

                "StartDateTime": "{{item.StartDateTime | Date: "yyyy-MM-ddTHH:mm:ssK"}}",

@Vivek Komarla Bhaskar Can you please confirm when you try to call the APIM endpoint directly then how much time it is taking to get the response. I want to confirm if this is the issue with the logic app or APIM end to assist you further.

As per the error looks like the HTTP trigger didn't get the response from the configured endpoint (APIM endpoint).

Hi @MayankBargali-MSFT
Response time is usually under 1 second, I've never seen a response that takes longer than that. A few times, the response took more than a second, but never longer than three seconds.

@Vivek Komarla Bhaskar , @Sonny Gillissen , @MayankBargali-MSFT , I'm running into this same issue and just came across this thread. The previous actions in my flow consistently take 1 second total, yet this timeout error on response still occurs occasionally. Did this issue ever end up getting resolved, and if so, how?

Hi Vivek,

You can increase the timeout in API Management by setting the below policy:

<backend>
        <forward-request timeout="300" />
</backend>

Did it start today? I'm experiencing the exact same issues on my APIM's, so I think there is some issue with the underlying infrastructure. I'm checking it now, and otherwise going to log a ticket at Microsoft.

No, I have been noticing this issue over the past 2-3 weeks. In between 2-3 weeks for a couple of days, it was fine but I again started to see this happening. Please let me know when you have a solution

Sorry for the late response, @Vivek Komarla Bhaskar but have you tried the 'Diagnose and solve problems' in the plane and selected 'Performance' ? Can you tell me if anything is noted there?

Hello @Sonny Gillissen

The troubleshooting performance shows no results even though I had failures for the same issue in the last 24 hours. Here are the screenshots -
