What this category of data looks like
Data sources for municipal waterworks service inquiry and response include official service systems, pipeline operation and maintenance databases, and user inquiry archive databases. Update rhythms fall into three categories: real-time monitoring data such as pipeline pressure and flow is updated per second; service work orders and billing data are updated daily; the common problem knowledge base is synced weekly. The document structure includes structured fields and unstructured text. Structured fields include item number, processing node, material list, charging unit price (unit: yuan per cubic meter), and more. Unstructured text includes service guide details, original user inquiry response texts, and more.
What constraints these characteristics impose on the "workflow orchestration" link
Second-level real-time updates require workflows to avoid excessive caching, otherwise inquiry content will lag behind current waterworks status. The fixed format of structured fields requires workflow form input nodes to match field types. For example, the charging unit price field must restrict non-numeric input. Daily updates of service work orders require the workflow's scheduled trigger node to execute synchronization on a daily cycle. Weekly updates of the common problem knowledge base require the knowledge base recall node in the workflow to match that synchronization frequency. There are many types of waterworks service items, so workflow branch judgment is needed to match the corresponding processing path based on the item type entered by the user.
How to set the configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Form input node trigger rule | Only hide dialog boxes within the current workflow, disable pop-ups when nested | Matches the user interaction scenario of municipal waterworks service inquiries, avoids repeated pop-ups during nested calls |
| Knowledge base sync cycle | 7 days | Matches the weekly update rhythm of the common problem knowledge base, reduces invalid sync operations |
| Workflow timeout threshold | 300 seconds | Adapts to the conventional response time of waterworks data queries, avoids degraded user experience from long waits |
| Context window size | 2000 token | Matches the text length of waterworks service inquiries, avoids exceeding the model's processing limit |
variables configuration | Bind exclusive fields such as pipeline pressure, charging unit price, etc. | Matches the structured characteristics of municipal waterworks data, ensures accurate parameter transfer |
nodeId configuration | Bind fixed IDs of form nodes and knowledge base recall nodes | Ensures stable branch judgment logic, adapts to workflow branches for multiple types of waterworks service items |
| Number of single recall results | Top 6 entries | Matches the number of common questions for waterworks service items, avoids information overload that affects response speed |
Three common misconfigurations
- Scenario: Returns error status code 500 when calling a custom Python code function. Cause: Failed to configure the correct dependency package import path in the workflow's code node, resulting in missing dependencies.
- Scenario: Dialog boxes continue to display when a form input node is nested in a parent workflow. Cause: Failed to turn off the switch to hide pop-ups in nested scenarios in the form node's trigger configuration, resulting in the global pop-up rule not taking effect.
- Scenario: Workflow runtime exceeds the preset threshold. Cause: Failed to limit the number of single recall results, resulting in too many knowledge base documents being loaded, slowing down runtime.
How to confirm the configuration is correct
- Trigger a test form submission, check whether the exclusive field values for waterworks services are correctly passed in the workflow logs.
- Check the execution records of knowledge base sync tasks, confirm that updates are completed according to the preset cycle.
- Simulate a nested workflow call, confirm that the dialog box of the form node does not display.
- Run the workflow and check the runtime logs, confirm that the preset timeout threshold is not exceeded.
