Error message

error copying file from ${details.absolutePath} to ${publicPath}

What it means

extend-file-node's publicURL-style resolver copies the source file into public/static/<contentDigest>/ on first request; this panic fires from the copy callback when fs.copySync reports an error (permissions, missing source, disk issue) while copying details.absolutePath to publicPath.

Solutions

1. Check the source file exists and is readable at the logged absolutePath.
2. Verify the build process has write permission to the public directory and enough free disk space.

When it happens

Trigger: Thrown at packages/gatsby-source-filesystem/src/extend-file-node.js:39 when the library encounters an invalid state.

Common situations: Occurs when copying a file node into the public folder fails, typically due to filesystem permissions or a missing source file. Check that the source path exists and the process can write to the public directory.
