This document is written for FastGPT v4.17.0. The following content applies to the workflow orchestration features of this version.
What the data for this category looks like
Data sources for this category include terminal management platforms, asset systems, user trouble reporting channels, and software repositories. Daily generated documents include terminal trouble tickets, installation inventory lists, software installation records, and remote assistance records. Data is updated either daily or synchronized with individual requests. Document fields include terminal unique identifier, trouble type, processing node, associated software version, user trouble reporting time, and other relevant fields. There are no mandatory additional statistical units, and field formats are matched based on business scenarios.
What constraints these characteristics impose on workflow orchestration
Decentralized data sources require workflow configurations to include cross-source data pull nodes, to connect to multiple data sources such as terminal management platforms and asset systems. Unstandardized daily document structures require built-in field validation rules to adapt to format requirements for different document types, including trouble tickets and installation inventory lists. Flexible update frequencies require workflows to support on-demand or scheduled triggering, to avoid invalid data requests. Time-consuming trouble troubleshooting steps require embedding automated troubleshooting nodes in the workflow, to reduce manual repetitive operation steps.
How to set configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
variables | Bind three core fields: terminal ID, trouble type, and user trouble reporting time | Match the core business fields of daily documents to ensure accurate data transfer between workflow nodes |
nodeId | Assign unique identifiers to cross-source data pull, field validation, and automated troubleshooting nodes | Distinguish between different functional nodes to avoid node conflicts during workflow execution |
| Global variable scope | Set to globally shared | Adapt to business requirements where outer workflows and nested sub-processes share variables |
| Timeout threshold | 300–600 seconds | Match the typical response duration for terminal data pulls, to avoid task interruptions caused by network fluctuations |
| Single data pull limit | First 10 entries | Match the typical upper limit of single returns for terminal data |
| Field validation rules | Match required fields by document type | Adapt to format requirements for different documents such as trouble tickets and installation inventory lists |
Three common mistakes
- Symptom: No knowledge base reference option appears in the variable selection panel of the code run node. Cause: The knowledge base associated field is not bound in the
variablesconfiguration, causing the workflow to fail to recognize the knowledge base data source. - Symptom: The workflow returns status code 500 during execution, prompting that the global variable is undefined. Cause: The global variable scope is not set to globally shared, so nested sub-processes cannot read variables from the outer workflow.
- Symptom: The
REDIS_URLvariable configuration does not take effect. Cause: This environment variable is not declared in the workflow'svariablesconfiguration, causing nodes to fail to read system configuration parameters.
How to confirm the configuration is complete
- Trigger a test workflow, check if the variable dropdown options for each node include the preset terminal core fields.
- View the workflow's node ID list, confirm that all functional nodes have been assigned unique identifiers.
- Submit simulated terminal trouble ticket data, verify that the field validation rules block non-compliant content.
- Start a nested sub-process, confirm that variables from the outer workflow can be read normally in the sub-process.
