Internal Error: Unable to understand where to start

I am getting the following error message in the IDE when trying to run. Any pointers on where to start would help, as I am clueless…

The browser log simply says

: TypeError: Cannot read properties of undefined (reading 'properties')
: TypeError: Cannot read properties of undefined (reading 'properties')

The error dialog popup says
Uncaught TypeError: Cannot read properties of undefined (reading 'properties')

Are you able to provide clone link, that way we can investigate

Can’t share a public link, I have shared it with you in a dm

FYI, this error happened after I copied a number of client forms and renamed them

e.g. I copied form plan_inputs_cpp_params and renamed it plan_inputs_cpp_params_d … and so on

Something seems off with the form copy…it seems to be stuck (note the same file names…)

Hi @ananth,

This should now be fixed. Please let us know if you’re still seeing the issue!
