Hi there,

Using the following component produced the error detailed below. This component worked in XOD version 0.20.3 :-  
Component:- text-lcd-16x2  
xod/common-hardware/text-lcd-16x2  
Drives a text LCD screen with HD44780 chip

Error  
UNEXPECTED\_ERROR {“message”:“Can’t find the patch in the project with specified path: “xod/core/constant-port””}  
The error has no formatter, which is a bug. Report the issue to XOD developers.

Hi!

It’s most likely because you have an outdated copy of `xod/core` library lying around in your workspace. Do you have ` __lib__ /xod` folder there? Just delete it and all should be fine.

Thank you,

Found it hanging out here …. $HOME\xod\__lib_\_\xod\core  
Renamed it $HOMEC\xod\__lib_\_\xod\core\_old (will delete it)  
Works fine now.
