I recently installed Gimp 3.0.0-RC1 using the windows installer (on Win 11 - 64-Bit).
I am new to plug-in development, having only written one plug-in for Gimp 2.10.38 just last week. The 2.10 plug in works as I expect it to. In learning plug-in development, I discovered 3.0.0-RC1 and decided to install it and convert my plug-in to work with 3.0. To start, I attempted to create a simple, "Hello, World!" plug-in. Currently I have:
I can select the plug in from the menu just fine, but I am not seeing output in the Error Console (as I think that is where Gimp.message() outputs the message) and I am seeing the following error in the terminal window:
I have tried google the error messages but only found one thread regarding foggify that didn't seem to provide a relevant fix. I also read the thread regarding the "group-selected-by" plug-in and followed some suggestions in that thread to update my code but I am still seeing the error....
Any help to resolve this would be great....

##UPDATED function definition to remove 'run_data' parameter

# function code goes here...
Gimp.message("Hello world!")
return procedure.new_return_values(Gimp.PDBStatusType.SUCCESS, GLib.Error())
Gimp.main(AnimateDrawableOffsets.__gtype__, sys.argv)
OK.....so, after re-reading the error message, I noticed it also included the line, " missing 1 required positional argument: 'run_data'"...removing this parameter from the definition for the run function allows the plug-in to operate and I can now see the "Hello, World!" message in the error console.....
I do not know what this parameter is for, or how removing it will affect the plug-in development. For now, I will keep researching what this parameter is used for and how it becomes populated with run_data.
