Cloud not convert stream / pdf to markdown

Hey there,

i wanted to generate a markdown of a really long pdf document (roughly around 100 pages). Simple print works, but as soon as it should be converted to markdown, it gives the following issue below. Is there a now limitation to the length of a document?

Traceback (most recent call last):

Start with script/markdown.py and the convert, convert_local, and _convert paths in packages/markitdown/src/markitdown/_markitdown.py. Reproduce the failure with the reported roughly 100-page PDF and inspect why no converter attempts conversion. Done means determining whether document length or unsupported PDF detection causes the failure and documenting or correcting the observed behavior.
