Password protected documents are not handled successfully

[tadasauciunas]

In our use case, password protected documents are quite common. People try to preview them, and the lambda conversion function fails because obviously the files are encrypted. I do believe that it's expected behavior for these conversions to fail, but fail in a user-friendly manner.

Currently, this case ends up in a JS error: Cannot read property '1' of null It's thrown by this line of code https://github.com/shelfio/aws-lambda-libreoffice/blob/ab4dde6f041498bd78c7773ae5a9103cb71153db/src/logs.ts#L2 Because output of soffice --convert-to command outputs some error instead of converted file path

I might provide a pull request to somehow avoid this in the near future. I think the easiest solution would to find an easy way of finding out whether a file is encrypted or not, but a quick google search did not help me out. Perhaps somebody else has a better solution ?

EDIT: I noticed there has already been an issue regarding this problem, but hopefully I or somebody else will come up with a solution this time. https://github.com/shelfio/aws-lambda-libreoffice/issues/28

Hi @tadasauciunas . My ask is a little different from the one you posted but on the same subject. I want to know the parameter to pass the "password" in the soffice command so that the word document opens and converts to a pdf. Currently, all my docs without passwords work fine except for the ones with passwords.

The error I am getting is -
