Error: pandoc document conversion failed with error 6

I tried to knit a document and received the following error code:

output file:
Unknown option -3.
Unknown option
Try pandoc --help for more information.
Error: pandoc document conversion failed with error 6
Execution halted

I looked at this thread and it seems that I have the right version of pandoc:

[1] "/Applications/"
[1] ‘3.1.1’

[1] "/Applications/"

[1] "/Applications/"

What is the name of your document ? Does it have dash in it ? or even start with a dash ?

It seems the name could be a problem when passed to pandoc as command line argument

Document name does not have dashes

No dash but it starts with a non alphanumeric character. (1). Probably in your example shared before it was (3). Parenthesis are special character in file name so it is replaced by -, hence the starting dash in Pandoc's error.

This is related to this issue

and we'll try to improve and fix this for next version
