What the data for this category looks like
The data for declaration materials and case review of telecommunications engineering construction primarily comes from official documents and business forms across the full lifecycle of project initiation, approval, and acceptance. Data sources include project initiation application reports, on-site survey records, budget preparation forms, acceptance opinions, and more. Update frequency adjusts based on project progress. Initial materials are uploaded in bulk during the initiation phase, and new files are added as needed during approval and acceptance stages. Document formats are primarily PDF and Word, with structured Excel budget forms as supporting materials. Fields include unique project ID, construction location coordinates, budget amount (unit: ten thousand yuan), construction unit qualification number, current approval node status, and others.
What constraints these characteristics impose on the workflow orchestration link
The mixed-format data feature of declaration materials and case review for telecommunications engineering construction requires workflows to adapt to differentiated parsing logic for PDF, Word, and structured Excel files. Do not rely on a single text extraction node. Unique project ID serves as the core identifier, and must be bound as a global variables to ensure data isolation between different project cases. Status changes of approval nodes must trigger subsequent stages. For example, receiving project initiation approval automatically starts the budget review branch. Uploading large-volume survey reports and acceptance documents requires configuring appropriate timeout thresholds to prevent workflow interruptions from file transfer timeouts. Field extraction from structured budget forms must match preset business fields to ensure subsequent review links can directly call corresponding data.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Bind project ID and construction location fields | Ensure data isolation between different telecommunications engineering cases, and enable precise calling of corresponding business data in subsequent review links |
| File upload node timeout | 600 seconds | Survey reports and acceptance documents for telecommunications engineering are usually large in size, requiring sufficient transmission time |
nodeId | Bind the unique identifier of the current parsing node | Ensure independent configuration for each parsing node, avoiding parameter conflicts between different nodes |
| Multi-format parsing nodes | Enable PDF parsing, Word parsing, and Excel structured extraction in sequence | Adapt to the mixed-format characteristics of declaration materials, avoiding failures caused by a single parsing logic |
| Workflow branch trigger | Trigger based on approval node status | Match project progress rhythm, starting subsequent review links only after receiving corresponding approval documents |
Three Common Configuration Mistakes
- Symptom: A "Failed to create post presigned url" error is returned when uploading engineering survey files via the workflow. Cause: The timeout threshold for the file upload node is not configured correctly, or insufficient network bandwidth causes a timeout when generating the pre-signed URL.
- Symptom: After calling the workflow API to pass image parameters, the parsing result is empty or an error occurs. Cause: Image file parameters are not passed in the format required by the API documentation, or the image parsing configuration in the multi-format parsing nodes is not enabled.
- Symptom: Large language model outputs from workflow nodes include irrelevant historical project data. Cause: Node context isolation is not configured, and the global context is inherited by default, leading to interference from redundant data with the current review.
How to Verify a Successful Configuration
- Upload a typical telecommunications engineering declaration material, and check whether the workflow triggers parsing and review links in the preset order.
- View the workflow variable panel, and confirm that fields such as project ID and construction location have been correctly bound to
variables. - Call the workflow API to upload a test file, and check whether the returned result only includes data related to the current test project.
- Trigger a single review node individually, and confirm that its output is only based on the input data of the current node, with no global redundant content introduced.
