UiPath Core

PyPI - Version PyPI downloads Python versions

Core abstractions and contracts for the UiPath Python SDK.

Installation

pip install uipath-core

Modules

Errors

Exception hierarchy for UiPath trigger errors with category-based classification.

  • ErrorCategory: Enum: DEPLOYMENT, SYSTEM, UNKNOWN, USER
  • UiPathFaultedTriggerError: Base trigger error with category and detail
  • UiPathPendingTriggerError: Pending trigger variant
from uipath.core.errors import ErrorCategory, UiPathFaultedTriggerError

Serialization

JSON serialization utilities for complex Python types. Handles Pydantic models (v1 & v2), dataclasses, enums, datetime/timezone objects, sets, tuples, and named tuples.

  • serialize_json(obj): Serialize any object to a JSON string
  • serialize_defaults(obj): Custom default handler for json.dumps()
from uipath.core.serialization import serialize_json

Tracing

OpenTelemetry integration with UiPath execution tracking. Provides function instrumentation, span lifecycle management, custom exporters, and batch/simple span processors with automatic execution.id propagation.

  • @traced: Decorator for sync/async function instrumentation. Supports custom span names, run types, input/output processors, and non-recording spans
  • UiPathTraceManager: Manages TracerProvider, span exporters, and processors. Provides start_execution_span() context manager and span retrieval by execution ID
  • UiPathSpanUtils: Span registry and parent context management
  • UiPathTraceSettings: Configuration model with optional span filtering
from uipath.core.tracing import traced, UiPathTraceManager

@traced(name="my_operation", run_type="tool")
def do_work(input: str) -> str:
    return process(input)

Guardrails

Deterministic rule-based validation for inputs and outputs. Rules are evaluated pre-execution (input-only) and post-execution (all rules), with flexible field selection using dot-notation paths and array access ([*]).

Rule types:

  • WordRule: String pattern matching
  • NumberRule: Numeric constraint validation
  • BooleanRule: Boolean assertions
  • UniversalRule: Always-apply constraints

Field selection:

  • AllFieldsSelector: Apply to all fields of a given source (input/output)
  • SpecificFieldsSelector: Target specific fields by path

Service:

  • DeterministicGuardrailsService: Evaluates guardrail rules against inputs/outputs, returning GuardrailValidationResult with pass/fail status and reason
from uipath.core.guardrails import DeterministicGuardrailsService, GuardrailValidationResultType

Chat

Pydantic models for the UiPath conversation event protocol. Defines the streaming event schema between clients and LLM/agent backends.

Hierarchy:

Conversation → Exchange → Message → Content Parts (with Citations)
                                  → Tool Calls (with Results)
                                  → Interrupts (human-in-the-loop)

Supports session capabilities negotiation, async input streams (audio/video), tool call confirmation interrupts, URL and media citations, and inline/external value references.

from uipath.core.chat import UiPathConversationEvent, UiPathSessionStartEvent
