Child Task 840897391 failed: Error parsing manifest: Manifest file count (6742) greater than maximum allowed (6000)

...I created a Shiny app and when I try to deploy it, I get the following error

Child Task 840897391 failed: Error parsing manifest: Manifest file count (6742) greater than maximum allowed (6000)

I checked for hidden files in the directories and removed them. Yet I get this error. Is there way to find out what is causing this problem? Though this question has been asked in this community it does not seem to have been answered.

Is there a way to dump the manifest file? There are no logs or any files generated which helps in debuggung the issue. I have no way of knowing what is causing the issue.

Any help will be appreciated.
