UiPath LLM Client [v1.17.0]

[1.17.0] - 2026-07-14

Changed

• Restored retry parity with the legacy uipath-langchain-python chat-client retryers (BedrockRetryer) that the shared transports replaced. Under throttling that outlasted the previous budget, runs that the legacy client absorbed silently were now failing.
  • Default retry budget is now 5 attempts (was 3) with exponential backoff starting at 5s (was 2s) capped at 120s (was 60s) — waits of ~5/10/20/40s, an absorption window of roughly 75s instead of ~6s.
  • Retry-After / x-retry-after is honored on any error status, not just 429: the header caps the wait for every UiPathAPIError, and its presence forces a retry even for otherwise non-retryable statuses (an explicit server retry request). retry_after moved from UiPathRateLimitError up to UiPathAPIError.
  • HTTP 524 (Cloudflare origin timeout) is retryable again via the new UiPathOriginTimeoutError; 529 remains retryable.
  • Connection-level failures are retried: httpx.TimeoutException (connect/read/write/pool timeouts), httpx.ConnectError, and httpx.RemoteProtocolError — the union of what the legacy Bedrock (botocore timeout/connection errors) and Vertex (httpx timeouts, connect errors, remote-protocol errors) retryers handled.

Added

• UiPathOriginTimeoutError (HTTP 524), exported from uipath.llm_client.
