Can you try to make the commit title a bit more descriptive ? "fixing major bug" isn't wrong, but it doesn't tell much to the reader, either :)
Additionally, is that something we could have a test for ?

I can probably write a test code to reproduce it, but it will start up a rest server, so not sure if it is a good idea to make it a unit test.

Thanks for investigating and fixing this issue guys! That would surely save a lot of time for next one who bumps into this issue!

@ferencdg in that case this folder seems like a good fit:
