Solutions

1. Send limit as a plain integer string (e.g. limit=50)
2. Coerce client-side number formatting to plain digits
3. Omit limit to use the default

Example fix

// before
fetch("/api/ai/agent/logs?limit=1.5")
// after
fetch("/api/ai/agent/logs?limit=50")

const limit = rawLimit?.trim(); if (limit && !/^\d+$/.test(limit)) throw new Error("limit must be a plain integer")

const isValidLimit = (v: unknown): v is string => typeof v === "string" && /^\d+$/.test(v.trim())

try { await api.fetchAgentLogs({ limit }) } catch (e) { if (e.status === 400 && e.message === "Invalid limit query") { /* send integer or omit */ } else throw e }

When it happens

Trigger: GET agent logs with ?limit=ten, ?limit=1.5, ?limit=-5 or other non-plain-digit strings.

Common situations: Client formatting numbers with separators; passing floats; buggy serialization of numeric params.
