Research direction
Investigate the 'marker was not found' error in jpeg js decoder.js at the decodeScan function (line 344). The error occurs intermittently, suggesting a race condition or corrupted JPEG data. Check how Jimp reads image files in @jimp/core/src/index.js and image bitmap.js. Consider adding debugging to log the JPEG data length and markers before decoding.
