What the data for this category looks like
Data sources for water treatment-related enterprises' financial reports include publicly disclosed periodic reports, internal operation ledgers, and industry regulatory submission documents. Quarterly data is updated 40 to 50 days after the end of each quarter. Annual data is finalized and archived by the end of March of the following year. Most documents are in PDF format or structured tables exported from online reporting systems, and contain three categories of content: operation modules, financial modules, and compliance modules. Fields include water treatment volume (unit: cubic meters), chemical agent unit consumption (unit: kg/thousand cubic meters), equipment operating hours (unit: hours), revenue (unit: yuan), compliance rectification expenditure (unit: yuan), and some fields are split by project.
What constraints do these characteristics impose on workflow orchestration?
Multiple data sources require workflow configurations with multiple docking nodes, plus data permission verification rules to distinguish call permissions between public data and internal data. The dual update cycles require setting two types of scheduled trigger rules, adapted to the workflows for quarterly financial report review and annual financial report audit respectively. The diversity of document formats requires dedicated parsing nodes for PDF and structured tables: enable precise table area extraction for PDF files, and skip the parsing step directly for structured tables. The dedicated unit rules for fields require configuring standardization rules during the data cleaning phase to unify measurement formats across different projects and avoid data confusion.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | PDF files for water treatment financial reports usually contain multiple pages of operation and financial data, with large individual file sizes. 1000 MB covers most scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Parsing multi-page structured financial reports requires a long time. 900 seconds ensures complete extraction of all table and field data |
TOOL_CALL_VALIDATE_MODE | strict | Strict verification mode blocks invalid JSON input containing control characters, resolving the Invalid JSON error that occurs during tool calls |
MODEL_ID | Select a text model with a context window ≥8192 | Water treatment financial reports include multi-dimensional field association analysis. Models with large context windows can process full datasets completely |
MCP_SERVICE_LOG_LEVEL | debug | Debug level outputs detailed request, response, and execution logs for the MCP service, facilitating troubleshooting of component operation exceptions |
WORKFLOW_NODE_CONNECT_ENABLE | Enabled | When enabled, the add circle for node connection lines displays normally, supporting workflow orchestration in data flow order |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- The symptom is the tool call node returning the
Invalid JSON: Bad control charactererror. The cause is that strict verification mode forTOOL_CALL_VALIDATE_MODEis not enabled, allowing invalid JSON input containing control characters to be submitted. - The symptom is the workflow editing interface failing to display the add circle for node connection lines, making it impossible to add connection lines between nodes. The cause is that the
WORKFLOW_NODE_CONNECT_ENABLEconfiguration item is disabled, or the switch is not activated. - The symptom is a timeout termination prompt appearing after workflow runs. The cause is that the value of
PARSE_FILE_TIMEOUT_SECONDSis not adjusted, and the default duration is insufficient to complete full parsing and data extraction for multi-page water treatment financial reports.
How to Verify Configurations Are Correct
- Upload a test water treatment financial report PDF, check whether the parsed fields are complete and whether the units comply with the preset standardization rules.
- Drag two workflow nodes to the editing interface, check whether the add circle for connection lines displays normally and whether data flow relationships can be established.
- Input test text containing control characters in the tool call node, check whether the input is blocked by verification or returns a corresponding error.
- View workflow operation logs to confirm that detailed request and response content for the MCP service can be output normally.
