Ruby bundler version error

Question & Answer
1

Hi, I’m getting an error with my scraper:

You must use Bundler 2 or greater with this lockfile.

I assumed the runtime would honour my .ruby-version and Gemfile.lock which specify ruby 3.1.4 and bundler 2.3.25.

here’s the scraper and I assume you can see the log output morph.io: heathd/civil_service_jobs

any ideas?

Longer log output below:
