What the data for this category looks like
Data for urban investment platform policy and regulatory basis comes from internal compliance archives, publicly released urban investment operation policy documents from provincial finance and housing and urban-rural development departments, and normative documents issued by local people's congress standing committees. Public policies sync in real time when released. Internal systems update immediately upon revision. Documents use structured entries as their core. They include policy document numbers, issuing entities, effective dates, applicable scenarios, and specific clause content. Fields cover policy classification, applicable regions, and responsible departments. Units are mostly clause items and document pages. Dates use standard year-month-day format.
What constraints do these characteristics impose on the "workflow orchestration" link?
The above data characteristics create multiple constraints for workflow orchestration. Scattered public and internal data sources require workflow configurations to include multi-source pull nodes that cover public platforms and internal archives. The uniqueness of policy document numbers requires workflow variables to be bound to policy document number parameters for precise recall. The presence of region fields requires the workflow to add an applicable scope filtering step to prevent cross-region policies from being incorrectly recalled. The clause-based document structure requires chunking logic to split by single clauses to ensure context integrity. The lack of fixed update cycles requires the workflow to support flexible adjustment of synchronization frequency.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
variables | Pass policy document numbers, applicable regions | Urban investment policies require precise matching of document numbers and regions to avoid cross-scenario recall |
nodeId | 24-digit hexadecimal characters | FastGPT v4.17.0 requires workflow node IDs to use this format |
| Data source synchronization frequency | Once per week | Public urban investment policy updates have no fixed cycle, weekly synchronization covers most updates |
| Context length | 800–1200 characters | Single clauses in urban investment policies are mostly short paragraphs, this length can fully carry core content |
| Timeout setting | 600 seconds | Multi-data source pulls require longer response times to avoid mid-run interruptions |
| Result sorting | Sorted in descending order of policy effective date | Urban investment platforms need to prioritize displaying the most recently effective policy basis |
Three common mistakes
- The symptom is an "invalid node identifier" error returned when calling the workflow. The cause is failure to use the 24-digit hexadecimal character format
nodeIdparameter, or input of a non-standard node ID. - The symptom is an axioserror triggered by a code node. The cause is failure to configure the correct API access address and secret key in the workflow, or failure to correctly bind query parameters to
variables. - The symptom is recalled policy documents that do not match the query scenario. The cause is failure to bind the applicable region parameter to
variables, leading to incorrect recall of cross-region policies.
How to confirm the configuration is correct
- On the FastGPT backend workflow management page, check the
nodeIdfield to confirm it uses the 24-digit hexadecimal character format. - Manually trigger the workflow, pass test policy document number and region parameters, and check if the returned context includes the corresponding policy clauses.
- Check the data source synchronization logs to confirm that pull tasks for public policies and internal documents run at the set once-per-week frequency.
- Simulate user queries to verify that recalled policy documents are sorted in descending order of effective date.
