profile-does-not-exist

Error message

profile-does-not-exist

What it means

Thrown by UpdateParent when GetUserProfile(userId, dto.Id) returns null — the target reading profile that should be merged into the series' parent profile does not exist for the user. The literal 'profile-does-not-exist' is a localization key surfaced to the UI. UpdateParent deletes the named profile and applies its settings onto the resolved parent profile.

Solutions

1. Refresh the user's reading profile list and retry with a current profile id.
2. Verify the profile id belongs to the requesting user and still exists.
3. Handle the not-found case gracefully in the UI instead of retrying the same stale id.

var exists = await unitOfWork.AppUserReadingProfileRepository.GetUserProfile(userId, dto.Id) is not null;
if (!exists) return NotFound("profile-does-not-exist");
await profileService.UpdateParent(userId, libraryId, seriesId, dto, activeDeviceId);

public static bool ProfileFound(AppUserReadingProfile? p) => p is not null;

try { await profileService.UpdateParent(userId, libraryId, seriesId, dto, activeDeviceId); }
catch (KavitaException ex) when (ex.Message == "profile-does-not-exist") { return NotFound(); }

When it happens

Trigger: Client sends a profile id (dto.Id) that was already deleted, belongs to another user, or never existed; concurrent profile edits deleted it between load and update.

Common situations: UI had a stale profile id after another tab deleted it; profile was reset/cleared; id mismatch after a data migration.
