Bug description

My deployment is failing

How to reproduce the bug

I am trying to do some simple edits to my homepage. The last time I successfully pushed edits was in October of 2024. Today, my deploys failed with warnings Your workflow is using a version of actions/cache that is scheduled for deprecation, actions/cache@v2. Please update your workflow to use either v3 or v4 of actions/cache to avoid interruptions.

and

The set-output command is deprecated and will be disabled soon. Please upgrade to using Environment Files.. I changed my deploy.yml file to use actions/cache@v4 and I changed the syntax of the set-output commands to match the syntax on this site.

However, the deployments are failing with the error message given below.

Your code must be based on a really old version. Have you tried updating your deploy.yml to the latest version, but keeping some of your actual code? For instance, replace your entirely deploy.yml with the current one, but add this line:

npm install -g mermaid.cli

Since we removed mermaid as a dependency a while ago. Also, you might need to update your Gemfile and Gemfile.lock versions. You are probably using a lot of older libraries that have been/are going to be deprecated.

Of course, I'd recommend updating your repository to the latest version, but that probably will require some work.
