Pull request overview
This PR extends the UiPath Python SDK/CLI to (1) allow projects to plug in a custom chat bridge via uipath.json so conversational agents can run against non-CAS surfaces (e.g., Slack/Teams/webhooks) both locally and when deployed, and (2) add a new Orchestrator jobs API to resume suspended jobs that have no “inbox” (common for conversational exchanges that end suspended).
Changes:
- Add
chatBridgetouipath.jsonschema and resolve/load a project-provided bridge factory at runtime. - Update
uipath runexecution flow to use the project chat bridge even when not running under a platform job. - Add
jobs.resume_job/resume_job_asyncand tests for resuming a suspended job by key without an inbox.

🚨 Heads up:

…t an inbox a conversational agent can only speak to the conversational agent service today. projects can now name a chatBridge in uipath.json and reach any surface, and a job that suspended without an api trigger can be resumed at the job level.

a conversational agent can only be spoken to through the conversational agent service today. everything the runtime needs to reach another surface is already framework agnostic: every runtime emits
UiPathConversationMessageEvents andUiPathChatRuntimeconsumes them throughUiPathChatProtocol. only the factory was hardcoded, so langchain, llamaindex and coded agents all gain slack, teams or a webhook with no per-framework code.jobs.resumedelivers a payload to a job's inbox, which only exists when the job suspended on an api resume trigger. a conversational exchange ends suspended carrying no interrupt and therefore has no inbox, so it could not be resumed from the sdk at all.Development Packages
