Specified REPL directory "${directory}" contains no files

Error message

Specified REPL directory "${directory}" contains no files

What it means

Post-validation notice in gatsby-remark-code-repls's createPages: the configured REPL directory exists but readdir found zero files in it, so no codepen REPL redirect pages can be created and the step returns early with a console.warn. Missing directories/templates instead panic earlier.
