SOLVED - Launcher App - Error calling __commands::nuke_12.1v2((), {}): - UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 150: invalid continuation byte

Hello group,

We are using Shotgun and it’s pipeline for a couple of years now.
We’re in the process of updating the Pipeline to Python 3. Which hasn’t been smooth to say the least…

So we’ve installed the newest version of SG Desktop and set the env var SHOTGUN_PYTHON_VERSION = 3.

Desktop starts normally, but now on some machines we get the following error when we want to launch Nuke or Houdini. Now on most machines we can launch, but for some unknown reason we can’t on others.

It looks like for some reason in Python 3 mode it cannot properly decode a string. But why it does work on other machines is a mystery. So for now we have to revert back to python 2 on some machines. But this is not a nice sollution since some apps don’t work properly.
Now, I don’t want to fiddle with the App code itself, otherwise I have to change the code everytime we update the App in the future.

If anybody has a solution or other insights it would really make my day…

Cheers,

David

We saw similar error if user had international punctuation(unicode character) in his name. If we removed such characters it was working again. I’ve reported to AD and this is what they wrote back to me

Engineering team has confirmed it is a bug. The internal bug ticket is SG-6588. Because it is could be avoided by changing “i” to “i”. It won’t be on high priority to be fixed. I am sorry about that.

Our tracelog was this

Looks pretty similar

In our case it was “í” in your case seems to be “é”

Hi Ales,

Cheers for the quick reply.
You mean in the Shotgun user name? Of the system User name?

Cheers,

David

Shotgrid’s one, or better AD’s one, it was ok until we migrated to AD identity

Hey Ales,

As I said, you made my day :wink:
It was indeed a user with é
Had to change it in 2 places. In “name” en “first name” for anyone else who encounters this.

Cheers!
