Prompt Given

Fix test-application (3229), with failed step Install dependencies

Root cause: The test-application job in .circleci/config.yml was using a Docker image tagged circle-3.4.1, but both the Gemfile and .ruby-version specify Ruby 3.4.9. This version mismatch caused Bundler to abort with "Your Ruby version is 3.4.1, but your Gemfile specified 3.4.9" during the Install dependencies step.

Fix approach: Update the Docker image tag in the test-application job to use circle-3.4.9 so the running Ruby version matches what the Gemfile requires.

Changes made:

  • Updated .circleci/config.yml line 226: changed image tag from circle-3.4.1 to circle-3.4.9 in the test-application job's Docker executor
