Question

Getting error while calling a Web API using web activity

Varun Chandra 51

Hi,
I am calling an API in ADF using Web Activity. It is failing with the following error message. Error calling the endpoint ''. Response status code: 'ClientSideException HttpStatusCode : 408, HttpStatusString: RequestTimeout'. More details: Exception message: 'NA - Unknown [ClientSideException] A task was canceled.'. Request didn't reach the server from the client. This could happen because of an underlying issue such as network connectivity, a DNS failure, a server certificate validation or a timeout. Url endpoint request timed out. Please make sure the endpoint response is within 1 minute and retry. I have tried increasing HTTP RequestTimeout to 10 minutes. Then got the following error. Error : 504.0 GatewayTimeout Can anyone suggest a solution for this ? User's image

Hello @Varun Chandra , Thanks for the question and using MS Q&A platform. I could suggest you do the below.

Try to test the API call using other tools like postman or curl. If it succeeds there, then only try to implement that in Web activity (WA) .
I see that you are doing a POST, but it does not have a body, which I find it to be odd. Are you selecting the correct verb ?
The uri which you are trying to reach is this internet facing ? .If yes can you please share that with us . The 504 Bad Gateway Timeout Error can be of many reason

Hi @HimanshuSinha-msft , Thank you for the response. There was an issue with the API, which caused this error. It's working fine now.
There is a new issue. My pipeline has dependency on success of API. Web activity success let's us know about the connection & responses. How can we know if the work of API is completed before proceeding to next activity in ADF Pipeline ? Web activity calls an API which fills a table. That table will be used as source in next Dataflow. I would like to know whether the table is filled before starting the dataflow. Wait activity is not an optimal solution here. Could you please help with this ? My pipeline looks like this Get Metadata -> ForEach->Web Activity -> Dataflow.
