function app not reading / getting body in azure data factory?

Question

I have a simple azure data factory pipeline consisting on a function app that takes two pipeline variables and a fixed string as a third input as part of the body.

The function runs without problems in local dev. But when triggered in ADF it throws an exception indicating that the three params are None (no params received). Seems like it is not reading the body at all.

The body as set in ADF:

{"campaign_cycle": @variables('var_campaign'), "account_id" : @variables('var_account'), "status_msg" : "STATUS_OK"}

Also tried passing the variables values as variables('var_campaign') with no success

Any idea of what may be going on here?

Example run id : c8e5a78a-e4ee-415e-bd61-1ee22389c55e

regards

Hi @javier ,

Welcome to Microsoft Q&A Platform. Thanks for posting the query.

The issue is because it is not able to read the variable value and to consider evaluating the entire expression as a string, Please try passing the variables expression in double quotes as shown below or if its a string value you can use casting to string. I tested and it worked for me.

{"name":"@variables('test')"}  

Please let us know if the issue persists and we will be glad to assist further.
