Hi @DanG,

Could you please share a Loom with an overview of your setup, an example of the issue in the Debugger tab, and the Custom Function code and configuration? That would help us get a better understanding of what might be causing the function to error out.

Also, feel free to check out the Custom Function section in our Troubleshooting guide:
