PAPERCLIP_ADAPTERS_FILE could not be read at

Error message

PAPERCLIP_ADAPTERS_FILE could not be read at "${filePath}": ${(err as Error).message}

What it means

Env-bootstrap failure in parseAdapterRegistryEnv: PAPERCLIP_ADAPTERS_FILE points at a file path, but fs.readFileSync failed (missing file, permissions, etc.). Startup aborts with the underlying OS error message so the operator can fix the path or file mode.

Solutions

1. Check that the file at PAPERCLIP_ADAPTERS_FILE exists and is readable; fix the reported read error.
