What happended?
When attempting to generate migrations for a custom Medusa module with existing migration/snapshot files, the command fails because snapshotPath is undefined in the migration generation process.
Steps to Reproduce
- Install using
npx create-medusa-app@latest my-medusa-store - Create a custom Medusa module with a model definition
- Run command
npx medusa db:generate module_name, check migration folder and snapshot JSON file is created. - Make a change to the model definition
- Run command
npx medusa db:generate module_nameagain. - Observe the error
Expected behavior
Migration file gets generated
Actual behavior
Following error:
error: Failed with error The "path" argument must be of type string. Received undefined
error: The "path" argument must be of type string. Received undefined
TypeError: The "path" argument must be of type string. Received undefined
