The image file cannot be accessed — it's outside the allowed working directory (`/var/folders/…` vs `/Users/jheppler/work/chnm/pwd`), and the Read tool also flagged it as not a valid JPEG (the file header bytes don't match an image format, suggesting it may be a text/error response saved as `.jpg`). The file may not have downloaded correctly. If you're running the transcription script, check that the image fetch step is succeeding before passing paths to this transcription call.
