nbconvert not recognizing filepaths when appending .ipynb to the end of the filename

[4ci1ab]

nbconvert is only functional when excluding the .ipynb from the file path. Which results in a file render that omits the last letter of the rendered filename.

E.G.
nbconvert /content/drive/Shareddrives/filename.ipynb --to pdf

will not work or be recognized as a valid file path. But this will;
nbconvert /content/drive/Shareddrives/filename --to pdf

Which will render PDF files named, in this case;
'filenam.pdf'
