After completing my entire project, I encountered an error while running yarn build. The error message from Yarn is as follows:
Parse error on line 1:
^
Expecting "CALC", "LPAREN", "ADD", "SUB", "FUNCTION", "LENGTH", "ANGLE", "TIME", "FREQ", "RES", "UNKNOWN_DIMENSION", "EMS", "EXS", ...
got unexpected end of input
CompileError: Begins at CSS selector undefined
error Command failed with exit code 1
Despite all my efforts, including creating a new react app and transferring all files over, the error remains unresolved. It's frustrating as I don't believe I made any mistakes in my project setup.
