medium severityRetool AI Action blocks, Retool Agents, Vectors, LLM Chat (using Retool-managed keys)
AI Action blocks fail with HTTP 429 error and rate limit message. In apps: triggers error handler. In workflows (pre-fix): triggers success handler with populated `data.error`. Limits hit quickly (cumulative across Vectors, queries, etc.).
Root cause
Retool imposes strict hourly token limits on organization-wide usage of Retool-managed AI keys (e.g., 250k tokens/hour for most AI actions) to prevent abuse and restrict to non-production. Additional bug (pre-3.183.0): workflows treated 429 as success (populating data.error but not triggering error handlers).
