问题
My ADF pipeline has a lookup activity which uses a sql query to get data from a table and passes it to a web activity which posts the JSON to an API (azure app service). When the query gets 1000 rows it works fine but when I try over 5000 rows the web activity returns the error.
"errorCode": "2001",
"message": "The length of execution ouput is over limit (around 1M currently). ",
"failureType": "UserError",
When I post the 5000 rows to the API using postman it works fine. Any idea what this error means and how to resolve it?
Thanks in advance.

As you found, web activity has times out limitation for 1 minute. Also, based on the above error The length of execution output is over limit (around 1M currently)., web activity also has output size limitation for 1 MB.
You could find the limitation rules here and some of the them could be adjusted if you ask for Contact Support.
If nothing they can do,I provide you with a workaround that you could use ForEach Activity. Maybe you need to use paging query for your rest api and return a limited number of the data each time. Then query your data in loop until the number of return data is lower than threshold value.

Looks like the web activity times out after 1 minute if the endpoint its calling doesn't respond.
