I encountered the same mistake in this link: https://forum.coppeliarobotics.com/view ... hp?t=10162
I do not think this problem has been solved.

The complete error is:

Code: Select all

[/WorldFrame/youBot@childScript:error] [string "/WorldFrame/youBot@childScript"]:76: attempt to index a nil value (local
'fout')
stack traceback:[string "/WorldFrame/youBot@childScript"]:76: in function 'parseCSVFile'
[CoppeliaSim:error] External call to simCallScriptFunction failed ('parseCSVFile'): error in script function.

The .csv file is:
https://www.dropbox.com/sh/l9z8engd8hp3 ... xample.csv
the .ttt file is:
https://www.dropbox.com/sh/l9z8engd8hp3 ... ot_csv.ttt

I am using CoppeliaSim for Mac 13+ apple silicon. There is no error during installation.

Does anyone know what is the root cause of this?

You have some unhandled error in your model's script.

For the reasons io.open(... 'w') can return nil, see https://stackoverflow.com/questions/753 ... ile-handle
