What the data for this category looks like
Data sources for papermaking industry intelligent due diligence reports include industry association public statistics, customs import and export declaration data, raw material spot market monitoring data, financial reports and operation announcements of listed papermaking enterprises, and environmental protection department pollution discharge monitoring data, among others. Update cycles vary across data sources: raw material price data updates daily, industry production capacity and capacity utilization data updates monthly, and enterprise quarterly operation data updates quarterly. Documents include multi-dimensional fields such as per-ton paper pulp consumption, unit pollution discharge volume, annual production capacity, and downstream order volume. Each field has clear units, for example kg/ton, 10,000 tons/year, and cubic meters/ton. Each full report includes dozens of pages of raw data attachments and analysis content.
What constraints these characteristics impose on deployment and upgrade
Multi-source data with inconsistent update cycles requires configuring multi-source scheduled synchronization tasks during deployment, with differentiated timeout and retry strategies for each data source. Large single-report volume and long parsing times impose higher requirements on container memory and file parsing timeout configurations. Fields have specific units, so field validation rules must be configured during deployment to prevent data analysis errors caused by unit mismatches. During upgrades, compatibility between multi-source synchronization logic and field mapping rules must be maintained to avoid disrupting existing data processing workflows from version updates. Some data involves environmental compliance information, so sensitive data access permissions must be configured during deployment, and permission configuration consistency must be retained during upgrades.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Single papermaking due diligence report contains dozens of pages, so parsing takes a long time, and the default timeout duration is insufficient |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single report includes multiple raw data attachments, so its volume is generally larger than general documents |
SYNC_DATA_INTERVAL | 3600 seconds | Balances the real-time performance of high-frequency raw material data and resource usage of low-frequency industry data |
client_max_body_size | 2048m | Adapts to the upload requirements of large papermaking due diligence reports, and prevents Nginx from blocking requests |
MAX_CONTEXT | 8000–12000 characters | Retains sufficient report context to accurately recall relevant analysis content |
FIELD_MAPPING_VALIDATION | Enable unit validation | Papermaking due diligence data includes specific units such as kg/ton and 10,000 tons/year, so field matching validation is required |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: After Vercel automated deployment, accessing the service returns 404 not found. Cause: Environment variables specifying the backend service address were not correctly configured during deployment, so the frontend cannot properly connect to the backend interface.
- Issue: Startup fails after upgrading to version 4.9.2, with a prompt that the
systemEnvconfiguration item does not exist. Cause: Version 4.9.2 adjusted the nested structure of the configuration file. The hierarchy ofsystemEnvin the original config.json has changed, and the configuration was not updated according to the new version documentation. - Issue: After Nginx reverse proxies the FastGPT container, uploading large files returns 413 Request Entity Too Large. Cause: The Nginx
client_max_body_sizeconfiguration was not adjusted, and the default limit cannot adapt to the large file uploads of papermaking due diligence reports.
How to confirm the configuration is correct
- Upload a sample papermaking due diligence report file, check the parsing logs and page display content to confirm that the parsing progress completes normally without errors.
- Check the running records of multi-source data synchronization tasks to confirm that different data sources pull data at preset intervals without abnormal interruptions.
- Test the field mapping function, input test data with specific units to confirm that the validation rule normally blocks inputs with mismatched units.
- Access the reverse-proxied service address, upload a large test file to confirm that the upload process is not blocked or returns errors.
