Error message

error processing filter for signal: %s

What it means

GetSignalFilters loaded the stored quick filter for a single signal but NewSignalFilterFromStorableQuickFilter could not convert it. The stored row for that specific signal has a signal name or filter payload the current constructor rejects, and the error is wrapped with CodeInternal naming the failing signal.

Solutions

1. Check the signal string you passed vs what is stored for that org (the error suffix names the stored signal)
2. Inspect the stored filter JSON for that (org, signal) row and fix or delete it
3. Align app versions so the writer's format matches the reader's constructor
4. Reset the org's quick filters for that signal via UpdateQuickFilters to rewrite a clean row

try { return await getSignalFilters(orgId, signal); } catch (e) { if (/error processing filter for signal/.test(e.message)) { await resetSignalFilters(orgId, signal); return getDefaultFilters(signal); } throw e; }

When it happens

Trigger: Calling GetSignalFilters(ctx, orgID, signal) where the stored row's Signal value or marshalled filter JSON does not match what NewSignalFilterFromStorableQuickFilter supports (renamed/removed signal, malformed JSON blob).

Common situations: Version upgrade that renamed signals or changed the storable filter format, rows written by an older release, corrupted payload after manual DB edits.
