Every PDF import failed in production with "Setting up fake worker failed:
Cannot find module '/app/node_modules/pdfjs-dist/legacy/build/pdf.worker.mjs'".
output: "standalone" ships only the files Next's output tracer can see. It
traced pdf.mjs, because lib/invoice-parser.ts imports it by literal path,
but the worker's sole reference is a createRequire(...).resolve() call,
which the tracer does not follow. So the image contained pdf.mjs alone,
pdfjs fell back to its default "./pdf.worker.mjs" relative to pdf.mjs, and
the import hit a file that was never copied.
Copy the whole package in the runner stage: the worker has to sit next to
pdf.mjs, and so do the standard fonts, which the parser needs because it
passes useSystemFonts. Verified against the reconstructed runner layout —
the old layout reproduces the error verbatim, the new one parses and
extracts text.
Also in lib/invoice-parser.ts: workerPinned was set before the resolve, so
a failed resolve was never retried; and the empty catch swallowed the
MODULE_NOT_FOUND that named the real cause. Both fixed.
