I have an adf pipeline which calls the azure function to convert the string output to a valid json format. My pipeline works fine most of the time but some times i face this error while executing azure function activity


This is my pipeline

Can anybody tell any solution for this ?

    Hi @Amar Agnihotri ,

    Is the string that you are forming differ in size in every run? Like for clean runs, the size is lesser and sometimes it becomes a bigger payload with huge data?

    As per this documentation, the payload is limited to 896 KB.

    As a workaround, you can write the string to a table column or a blob file an access that from your azure function.

    Let us know
