decision(storage-resize-images): kit/extension parity – blank required params fail the kit deploy, the extension uses defaults #3327

storage-resize-images kit/extension parity. Priority: low. A config that works on the extension fails to deploy as a kit.

Difference

• Extension: a blank required param falls back to its declared default.
• Kit: assertRequiredParams() stops the deploy with Required parameters are set to an empty value: … when IMG_BUCKET, IMG_SIZES, DELETE_ORIGINAL_FILE, IMAGE_TYPE, FUNCTION_MEMORY or CONTENT_FILTER_LEVEL is blank in .env.

Reproduced

Seen in the code, not tested live on this kit.

Code

• Extension: required params at extension.yaml#L79, #L96, #L111, #L229, #L296, #L360.
• Kit: config.ts#L453-L488, called at index.ts#L35.

Resolution

Keep the stricter check, and mark which settings can't be blank in the README, as the firestore-bigquery-export kit README does (#3320).
