Hello All,
I am receiving a long error when opening my patch today. Everything seemed to be working well this morning, but upon returning to the project, I receive a long error in the Pd window:

(Tcl) INVALID COMMAND NAME: invalid command name "1994"
while executing
("uplevel" body line 56)
invoked from within
... plus a few more similar lines...

My GUI will no longer function properly and I am missing some objects (bangs, toggles, hslider).

When searching for 'Find last error' the message returns as 'no findable error yet.'

Using PD 51.4 w/Rosetta, M2 MacBook.

Any ideas on how to fix this issue? Thanks!

sounds like some gui object might have a bad send name or something.
only way to fix it is open your patch with a text editor and search for the offending string (in this case "1994") and repair it

either that or you've installed a non-working tcl plugin
posting all similar lines would be helpful as they show which tcl commands actully fail

Thank you for the direction. I opened the file as a text doc and was able to find the error.

In case anyone comes across a similar problem, my error was caused by the [playlist] object from the "unauthorized" external. Apparently, changing the [playlist] canvas size via the 'Properties' windows was causing major problems.

Thanks again for you help!

@jo Yes, you set the width and height for the external in it's arguments [playlist <extension> <width> <height>]
David.
