AzureFunction 504 timing out error while invoking from ADF.

Question

Hi Team, We have a problem of azure functions timing out when the scheduler in ADF triggers the pipeline which runs the Azure function. But at the same time, the azure goes fine when we manually run the ADF pipeline. As per the below documents. Our Azure function goes into sleeping mode as our process runs once a day. so, do we need to restart the function every day ?

Answer 1

@Anonymous Is your function in consumption plan ? That might be the cold start behaviour if its not working. You can try browsing the function app from the portal first and then run the adf pipeline. Other reason could be if execution is taking more than 230 seconds.
