Failed to process the image with ${fileStrategy}. ${error.me

Error message

Failed to process the image with ${fileStrategy}. ${error.message}

What it means

A wrapper thrown by processImage's catch block when the active file strategy's image processing throws. The original error is logged with logger.error and re-thrown prefixed with the strategy name (`fileStrategy`) and the original message. The actual root cause is in the logged error and the interpolated `error.message` — this is a pass-through that adds context about which storage/processing strategy failed.

Solutions

1. Read the server logs — the line just before this throw contains the original error from the strategy.
2. Verify storage backend health: disk space for local, credentials/connectivity for S3-compatible.
3. Reproduce with the exact file (it may be corrupt) and test sharp directly: `sharp(buf).metadata()`.
4. If the strategy is misconfigured, fix `getFileStrategy(appConfig, ...)` selection or the strategy's env vars.

try { await processImage(params); }
catch (e) {
  if (/Failed to process the image with/.test(e.message)) {
    logger.error('Image strategy failed', { raw: e.message });
    return res.status(500).json({ error: 'Image processing failed; please try again.' });
  }
  throw e;
}

When it happens

Trigger: Any unhandled exception from the configured image strategy: local filesystem write fails (disk full, permissions), S3/network storage upload fails (credentials, network), sharp processing throws (corrupt image, unsupported format), or the strategy's save/resize path rejects for any internal reason.

Common situations: S3 credentials rotated but the app still holds old ones; local uploads volume full or read-only in a container; sharp receives a truncated/corrupt upload; transient network error to object storage; a custom strategy plugin throwing an unexpected error.
