I am calling the Business Central web services of the custom API page from logic app. I am creating the Sales Header in the Business Central using this web service.

The web service is throwing an error ''Http request failed as there is an error: Received an invalid status line: 0.'. This error is not coming each time. We have the traffic like 2000-3000 web service calls per day and it failed 3-4 times. Also, when I re-run the web service it got succussed with the same web service payload and endpoint.

Business Central throws the error but that operation was also completed in the Business Central as Purchase Header will be created in BC and error is also received on web service response.

I checked it on logic app side, there is no issue on that side. So, Business Central is causing this issue.

One common cause of intermittent HTTP errors is the handling of persistent connections. You can try setting the KeepAlive property to false to ensure that each request establishes a new connection. This can help avoid issues with stale connections.

Given that the error occurs sporadically and resolves upon retry, you can monitor your Business Central API usage and adjust the request limits

Web service responds with an error, suggesting that the underlying connectivity or service handling may be affected during peak traffic periods. To mitigate this, consider implementing retry logic in your Logic App and closely monitoring the performance of Business Central during high traffic times. Additionally, reviewing the configuration and resource allocation may help improve overall reliability and reduce the frequency of these errors

I've been consistently facing this particular issue in my integrations developed using Logic Apps. In an attempt to resolve it, I migrated the integrations to Azure Function Apps, hoping the issue wouldn't occur there. Unfortunately, the same problem is also happening with the Function Apps.

Has anyone else encountered this behavior? Any insights or suggestions would be greatly appreciated.

This seems to be a problem with the Microsoft standard connector. It is recommended to submit an SR to allow Microsoft to assist in investigating this issue.
