ERROR:Response body is not valid JSON

When running, the start node generates an empty json and causes an error in the HTTP Request

Can someone help me?

Hey @Jovaldo_Savian,

I suspect the issue is not actually related to the start node and is actually the response coming back from the URL you are calling. If you change the response format to string do you get some HTML data back?

that was it, thank you.

But another problem arose, the list has 31 records, but only saves 30:


What is the rest of your workflow doing?

It’s pretty basic:
1- read data in firebase (finds 31 records)
2- Set two variables (name and email)
3- Post to an email list (where only 30 of the 31 records are registered)

Have you looked at the output of the node to see which one is missing?
