Hello,
I am getting an error for my data loader python file based on Job ID: It says “TypeError: Unicode-objects must be encoded before hashing”, does anyone have experience with this error? I am using standard template code for this function:
```auto
def getJobId(self):
"""
Return a unique string for each different select
:returns a string
"""
# Generate a stable id that changes with the main parameters
# m = hashlib.sha256()
m = hashlib.blake2b(digest_size=20)
m.update(repr(os.getcwd()))
job_id = m.hexdigest()
log.debug("Job ID: %s", job_id)
return job_id
```
ERROR:
```auto
Traceback (most recent call last):

I was able to figure out the issue. The reason was some of the code was outdated python2 code and needed to be adjusted. The key change being that the query needs to be encoded as utf-8 explicitly rather than implicitly as was previously possible with python2.
See below:
```auto
def getJobId(self):
"""
Return a unique string for each different select
:returns a string
"""
# Generate a stable id that changes with the main parameters
m = hashlib.sha256()
m.update(self.args.query[0].encode("utf-8"))
job_id = m.hexdigest()
log.debug("Job ID: %s", job_id)
return job_id
```

Where did you get this template code from?
The template I’m aware of at [training/custom\_plugin.py at 0422e9eaa291c63063712d286ff5addd965b8546 · squirro/training · GitHub](https://github.com/squirro/training/blob/0422e9eaa291c63063712d286ff5addd965b8546/templates/data/custom_dataloader_plugin/custom_plugin.py#L80-L94) has the right handling, which is to use `repr` and `encode` in combination to get the right input to the hashing function.
Your revised code does not necessarily handle the arguments correctly. It seems that `args.query` is a multi-value option, but only the first value will be used for the job id.

Yes I saw that Patrice. Did not realize that was the standard code that should always be in there.
What does Blake2b do?
I used another version because I didn’t realize this piece shouldn’t be customized. Good to know thanks
The first custom param and second custom param Is where I would include my arguments?
