Colorado court's staff added an announcement with the upcoming opinions to be released on the next Monday. The text broke the expected pattern to search for the listed opinions' date.

Also, the listed file is not an opinon, but a file listing issues which were addressed during oral arguments: https://www.courts.state.co.us/Courts/Supreme_Court/Oral_Arguments/Schedules/November%20orals%20docket.pdf
Since this page is edited by the court's staff at least one a week, I'll check it on Monday to verify for changes in the announcement text and to correct this error in the scraper's code.
We're getting faster at catching this kind of thing!
Colorado court's staff changed the announcement's text and updated the link to the opinion released today. The new text follows the expected pattern to search for the opinions' date; but a validation was added to avoid the error reported by Sentry.

The search for the optional citation for the opinions from the Supreme court was added to avoid scraping errors, like the one that occurred with the opinion released on February 7th, 2022.

This was resolved.
