Autograder Ignored file setting not working

[ace01603]

The assignment template I want to give to students includes extra files that they need while they are working but that are not needed by the autograder. When I test a submission by including these extra files, the upload fails and I get an error message, "Server responded with 500 code." I assume this is because the extra files (there are a lot) takes the submission over the maximum number of files permitted. Upload works fine if I manually remove the extra files.

Gradescope is supposed to have the capability to ignore files, which can be specified in Settings in the assignment GUI. The files are all stored in a folder called "lib", which is present in each question folder within the assignment template. I have tried to ignore all lib folders by adding them to the "Ignored" file box in the assignment settings (see screenshot), along with a few other files that dramatically increase the submission size for students on Macs. However, the files specified as "Ignored" are still uploaded, causing the submission to fail with a 500 error code. How do I fix this? Is there are way to specify files to ignore within the autograder itself, rather than the GUI?
