Translation Files Problem

Not on my main account, but this error basically pop ups whenever something goes wrong. The XLIFF export is a very, very fragile process.

The issue should not lie with the mapperfile, as that does not get changed during translation.

On the top of my head, I can think of the following problems:

BASIC PROBLEMS

1) Wrong folder

RH only accepts the folder where the XLIFFs and mapper file are directly stored. So you cannot select "XXX/translations", but you have to select "XXX/translations/{language_code}".

2) Wrong mapperfile

A mapperfile is created with each export, so make sure you select the correct mapperfile.

3) foreign files

The translation folder should only contain your translated .xlf files and the mapperfile, nothing else.

4) Xlf files are incorrect

Make sure the .xlf files are indeed translated .xlf files. You can take a sneak peek in an .xlf file to see if, for a given <trans-unit> tag, it has a <source> and <target> tag. If no target tags are found, then the .xlf files weren't translated.

FURTHER TROUBLESHOOTING

A mapper file is fundamentally just a dictionary with two keys, encryptedFiles and decryptedFiles. Basically, for each file listed in encryptedFiles/decryptedFiles, there should be a corresponding .xlf file in your translation folder. If that is not the case, this error will appear.

From a technical POV, I have no idea why a mapperfile is even needed as the information is also stored in each XLIFF file itself.
