Deluge and creator integration - creator connection does not exists

Hello, i've made a simple app in Zoho Creator, with a form and a report. Filled some records in the form and created the connection microservice (with read privileges on creator).

Then in my CRM i wanna make a connection between my customers and the data in the zoho creator app.

I've created a function with this code:

response = zoho.creator.getRecords("myuser","appname", "reportname", "", 1, 200, "connectionname");

but when i try the function, it says:

Connection 'connectionname' does not exist Line Number: 1

any suggestions?
