From adc947fb7f2d5a5a95ebe02759b9f486b4c5a2e8 Mon Sep 17 00:00:00 2001 From: Chibi Vikram Date: Fri, 9 Jan 2026 14:25:28 -0800 Subject: [PATCH 1/5] feat: add suspend/resume support for RPA invocations in evaluations Adds support for suspending and resuming evaluations that invoke RPA processes. When an evaluation suspends while waiting for an external job, it can now be resumed after the job completes. Changes: - Added SUSPENDED status detection after agent execution - Added --resume flag to 'uipath eval' command - Skip evaluator execution for suspended runs (evaluators run on resume) - Pass triggers through evaluation flow to enable resume - Added comprehensive logging for suspend/resume debugging Testing done with tool-calling-suspend-resume sample in uipath-langchain-python PR #414. --- src/uipath/_cli/_evals/_runtime.py | 119 ++++++++++++++++++++++++++++- src/uipath/_cli/cli_eval.py | 12 +++ 2 files changed, 130 insertions(+), 1 deletion(-) diff --git a/src/uipath/_cli/_evals/_runtime.py b/src/uipath/_cli/_evals/_runtime.py index adc1199e2..abc512d78 100644 --- a/src/uipath/_cli/_evals/_runtime.py +++ b/src/uipath/_cli/_evals/_runtime.py @@ -295,6 +295,8 @@ class UiPathEvalContext: report_coverage: bool = False input_overrides: dict[str, Any] | None = None model_settings_id: str = "default" + resume: bool = False + job_id: str | None = None class UiPathEvalRuntime: @@ -327,7 +329,8 @@ def __init__( self.trace_manager.tracer_provider.add_span_processor(live_tracking_processor) self.logs_exporter: ExecutionLogsExporter = ExecutionLogsExporter() -
