What the data for this category looks like
Telecommunications engineering construction teams source core data from construction site survey records, daily inspection ledgers, material inbound and outbound warehouse documents, and on-site image materials. Data is updated in daily inspection batches and weekly construction milestones. Each document includes structured fields and unstructured attachments. Structured fields include construction site latitude and longitude (unit: degrees, minutes, seconds), material codes, device models, and inspection times. Unstructured attachments are mostly CAD drawings and on-site photos, with a wide range of single-file sizes.
Constraints Imposed by These Data Characteristics on Tool Calling and Plugins
Telecommunications engineering construction data characteristics create three constraints for tool calling. First, structured fields include unit-specific dedicated fields such as latitude and longitude and material codes. Plugins must match corresponding format validation rules during calls to avoid parameter type incompatibility. Second, unstructured attachments have large sizes and diverse formats. Tool calling workflows must support chunked upload and format recognition to prevent single-transmission timeouts. Third, data is updated according to construction milestones. Tool calling must bind to the context of the current construction task to avoid cross-task data misuse.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| File upload chunk threshold | 100–200 MB | Matches the typical size of single CAD drawings or inspection images in telecommunications engineering construction scenarios |
| Parameter format validation switch | Enabled | Adapts to format requirements for dedicated fields such as latitude and longitude and material codes |
toolChoice | auto | Allows tools to automatically select the appropriate calling method based on the current task |
functionCall | Triggered per task | Enables fixed calling mode only when a specified tool needs to be invoked |
| Timeout duration | 600 seconds | Covers the time required for large attachment uploads and multi-step construction data validation |
| Result cache duration | 24 hours | Matches the update rhythm of daily inspection data |
Three Common Misconfiguration Errors
- Phenomenon: When calling a workflow via API, file upload fails with the error "file type parameters are not supported". Cause: File upload permission was not enabled in plugin configuration, and format validation rules for attachments in telecommunications engineering scenarios were not matched.
Reference only; verify against the target FastGPT release and deployment documentation.
- Phenomenon: When stream is set to true, received results are incomplete and have no end marker. Cause: No stream end judgment was added in the receiving logic, and all returned fragments were not concatenated.
How to Confirm Proper Configuration
- Upload unstructured attachments suitable for telecommunications engineering scenarios, and check whether tool calling can normally receive and parse the attachment content.
- Pass dedicated fields such as latitude and longitude and material codes when calling tools, and check whether the format validation rules are correctly matched.
- Call the interface with stream set to true, and check whether the receiving end can fully receive all streamed returned content.
- Configure
functionCallto be triggered per task, and check whether the corresponding tool is called only in the specified task scenario.
