[Self-Hosted] Module Progressions recursively corrupting (Completed with Requirements not met) after Upgrade

[Anand Srinivasan]

Hi everyone,

We manage a self-hosted Canvas instance and recently performed a major upgrade to [release/2025-03-12.361]. We are facing a persistent issue where Module Progressions are incorrectly marking students as Completed despite having met zero requirements.

The Symptoms:

1. A student interacts with a module (viewing/submitting).

2. The context_module_progressions record updates to:

   • workflow_state: 'completed'

   • requirements_met: [] (Empty Array)

   • This happens even though the Module definitely has active completion_requirements in the DB.

What we have verified:

• Integrity: The context_modules table has correct completion_requirements. All content tags exist and are published.

• The Fix Fails: We ran a script to destroy the corrupt progression records. This fixes the issue temporarily (status resets to Locked/Started). However, as soon as students interact with the course again, a percentage of records revert to the corrupt state.

• Strict Logic: We verified via Rails Console that progression.evaluate_requirements should be returning 'started' or 'unlocked', yet the record is being saved as 'completed'.

Environment:

• Canvas Version: [release/2025-03-12.361], same as [origin/stable/2025-03-12]

• Database: PostgreSQL 14

• OS: Ubuntu 24

It behaves as if the calculator sees the requirements as null during the write operation.

Any help on this is appreciated!

Thanks,
Anand
