node-rasa's Issues

[bug] Content is read by -2 offset

There seems to be a bug when reading content using either readFile or createReadStream. The returned content always contain the 2 last characters from the previous file and is missing 2 characters from the end. If the requested file is the first one in the asar archive, the first 2 characters are unrecognized binary characters.

The .asar archive was created using the asar package and can be read just fine by other packages like express-serve-asar.
