What the Data for This Category Looks Like
The data for tax-free intelligent due diligence reports comes primarily from customs clearance filing systems, off-shore duty-free shop sales ledgers, brand authorization documents, supply chain customs declaration documents, and compliance verification reports. Data update rhythms fall into three categories:
- Daily sales transaction data is updated daily
- Policy documents are updated irregularly per regulatory requirements
- Supply chain qualification files are updated per cooperation cycles
A complete due diligence report typically includes four core modules: supplier qualification pages, product filing details, monthly sales summaries, and compliance risk checklists. Fields include:
- Isolated Island Passenger Single Shopping Limit (unit: yuan)
- Customs Declaration Number (string format)
- Supply Chain Payment Term (unit: days)
- Product Filing Code
Some scanned attachment files can reach hundreds of megabytes in size.
What Constraints These Characteristics Impose on Deployment and Upgrade
Multiple heterogeneous data sources require configuring multi-format file parsing adaptation rules during deployment. This adapts to different formats such as CSV files exported from customs systems and PDF scanned documents provided by brands. Differentiated update rhythms require flexible switching between incremental and full synchronization. The upgrade phase must be compatible with existing synchronization logic and newly added real-time data pull interfaces. The large size and high page count of individual documents require adjusting parsing timeout and segmented processing parameters to avoid parsing interruptions. Special field units and coding rules require configuring field mapping verification rules. This prevents unit confusion or coding mismatches during data import. High compliance requirements in the tax-free field also require configuring relevant parameters for permission isolation and audit logs during deployment.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | A single tax-free due diligence report includes multi-page scanned documents and detailed tables, which take a long time to parse. 600 seconds covers most scenarios |
UPLOAD_FILE_MAX_SIZE | 2000 MB | A complete due diligence package includes high-definition customs declarations and sales ledger scanned documents, which usually exceed 1000 MB in size |
RECALL_TOP_K | Top 8 entries | Tax-free compliance verification needs to cover multi-dimensional content such as policy clauses, supply chain data, and sales records. 8 entries ensure core information is covered in recall results |
SIMILARITY_THRESHOLD | 0.75 | Precise matching of tax-free category exclusive policy texts is required to avoid interference from low-similarity irrelevant content in verification results |
basePath | /tax-free-due-diligence | Use Nginx to configure a secondary directory to isolate scene access and avoid conflicts with other deployment instances |
NEXTAUTH_URL | Calibrated via actual testing | Supports LAN or public network access. Must match the domain name or IP configured in the Nginx reverse proxy |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require on-site analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: The system cannot be logged in after modifying
ADMIN_PASSWORD, and the console reports "Authentication failed". Cause: The FastGPT backend and frontend services were not restarted correctly. Only modifying the configuration file did not trigger a reload. - Symptom: A 403 status code or connection timeout is returned when accessing the deployment instance via a LAN IP. Cause:
NEXTAUTH_URLwas not configured to the LAN IP, or the service listening port was not bound to 0.0.0.0, allowing only internal container access. - Symptom: Page static resources fail to load after configuring the secondary directory, and the console returns a 404 error. Cause: Only
basePathinnext.config.jswas modified, and theassetPrefixparameter was not configured synchronously, resulting in incorrect static resource paths.
How to Confirm Successful Configuration
- Upload a tax-free compliance document with more than 10 pages, wait for parsing to complete, and check the parsing log to confirm there are no timeout or format error prompts.
- Access the configured secondary directory address, verify that the page loads normally and the login entry jumps correctly.
- Modify the administrator password, execute the corresponding service restart command, and try to log in with the new password to verify that permission verification passes.
- After configuring the field mapping rules, upload a test document containing the "Customs Declaration Number" field, and check that the recall result correctly matches the corresponding field content.
