INVALID_MODULE for Custom Function

Hello, I am trying to run a simple custom function in the Projects module. I would like to update the name of a project based on some settings on the record. However, when I try to use zoho.crm.updateRecord("Projects",Id,updateMap); I get this error.

{"code":"INVALID_MODULE","details":{},"message":"the module name given seems to be invalid","status":"error"}

I have admin rights, is there something that I am missing? Most of the answers in here have been incorrect names for the module, but this is the right name. Any ideas what I am missing?
