Describe the bug
When starting the LWC dev server, an error is displayed "SyntaxError: Unexpected end of JSON input" and a message that the dev server is unable to start.
I was able to resolve the bug by searching within the SFDX project for empty (0 kb) JSON files. I found one file matching this criteria at {projectLocation}/.localdevserver/metadata.json. After updating that file with {}, the server was able to start.
Stack trace:
SyntaxError: Unexpected end of JSON input
