⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: backend/composer.lock

Command failed: composer update --ignore-platform-req='ext-*' --ignore-platform-req='lib-*' --no-ansi --no-interaction --no-scripts --no-autoloader --no-plugins

Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires johngrogg/ics-parser 3.5.1 (exact version match: 3.5.1 or 3.5.1.0), found johngrogg/ics-parser[dev-master, v1.0.0, ..., 1.0.4, 2.0.0, ..., v2.2.2, v3.0.0, ..., v3.5.0] but these do not match your constraint and are therefore not installable. Make sure you either fix the constraint or avoid updating this package to keep the one present in the lock file (johngrogg/ics-parser[v3.5.1]).
