Steps to reproduce

IconType enum (which only has IMAGE and EMOJI values), but the database can contain "link" as a value (see app_dsl_service.py line 431 where icon_type_value in ["emoji", "link", "image"]).

@dosubot[bot] commented on GitHub (Dec 30, 2025):

Yes, the IconType enum is missing the 'link' field. The enum currently only defines IMAGE and EMOJI, but the code that imports app data explicitly allows 'link' as a valid icon_type and stores it in the database if present. This creates a mismatch between the enum and the actual values that can appear in the database, which is recognized as a bug or inconsistency but hasn't been fixed yet. To resolve this, the enum should be updated to include 'link', or the import logic should be restricted to only accept values defined in the enum. Keeping these in sync is important to avoid runtime errors and confusion.
