What data for this category looks like
Data for financial software development intelligent due diligence reports comes from project initiation documents, code repository commit records, third-party financial compliance qualification documents, security vulnerability scan logs, and financial industry compliance requirement documents. Update frequency aligns with project iterations, with content refreshed after each version upgrade or compliance check. Document structures include fields such as project overview modules, technology stack list tables, code compliance description paragraphs, third-party dependency lists, and security vulnerability score entries. The technology stack field uses semantic version numbers, the vulnerability field uses the CVSS scoring standard, and code fragments are counted by line.
Constraints on document parsing and chunking
The multi-module structured nature of financial software development due diligence reports requires parsing to retain hierarchical relationships. This avoids damaging the integrity of structured data such as technology stacks and dependency lists. Documents often contain long compliance description paragraphs and code fragments. Chunking must preserve semantic coherence and avoid splitting cross-module content. Some reports use encrypted PDF files with digital signatures, so parsing must support content extraction after signature verification. High-frequency updates require parsing processes to have strong timeliness, preventing task failure from wait timeouts.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_MAX_SIZE | 200 MB | Software development due diligence reports often include code fragments and scan logs, so single-file volume is relatively large |
maxChunkSize | 800–1200 characters | Due diligence reports include technology stack descriptions and compliance paragraphs. This length preserves semantic integrity and avoids splitting critical information |
ENABLE_PDF_SIGNATURE_PARSE | Enabled | Software development due diligence reports often use compliant PDF files with digital signatures, requiring support for content extraction after signature verification |
RECALL_CHUNK_COUNT | First 6 entries | Technical modules in due diligence reports have high relevance, so sufficient context must be recalled to support compliance and technical solution analysis |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Parsing large-volume code scan logs and compliance documents takes longer. Extending the timeout prevents task interruption |
ENABLE_IMAGE_OCR | Enabled per scenario | Some due diligence reports include technical architecture diagrams in screenshot format, requiring OCR to extract text content |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common misconfigurations
- Issue: FastGPT V4.9.1 calling the Doc2x tool returns a file read error, with an error message containing
Only support .txt, .m. Cause: The allowed file suffix whitelist is not configured, and the commonly used.pdfand.docxformats for software development due diligence reports are not included. - Issue: Content cannot be recognized after uploading a digitally signed PDF. Cause: Encrypted PDF parsing configuration is not enabled, or relevant permissions required for signature verification are not configured.
- Issue: An error occurs when clicking the reading link returned by the API knowledge base. Cause: The signature expiration time for file access is not configured, or the corresponding access permission is not bound when generating the link.
How to verify correct configuration
- Upload a test sample of a software development due diligence report, and check if the parsed text retains core fields such as the technology stack list and vulnerability scores.
- Adjust the
PARSE_FILE_MAX_SIZEconfiguration, then upload a test file larger than 100 MB, and confirm that the parsing task starts normally without errors. - Upload a digitally signed PDF file, and confirm that the parsing result includes the compliance description text from the original document.
- Call the knowledge base interface, and verify that the returned context blocks include the corresponding module content of the due diligence report.
