--- BEGIN ISSUE ---
CA-SK production parser down
## Description

This is an automatic error report generated for Canada Saskatchewan (CA-SK).

Issues:
- No recent data found for `production` parser
- No recent data found for `consumption` parser

## Suggestions
- Try running the parser locally using the command `poetry run test_parser CA-SK production`
- <a href="https://storage.googleapis.com/electricitymap-parser-logs/CA-SK.html">Explore the runtime logs</a>

You can see an overview of all parser issues [here](https://github.com/tmrowco/electricitymap-contrib/wiki/Parser-issues).
