What the data for this category looks like
The marketing content data for the solid waste treatment sector primarily comes from internal enterprise project ledgers, environmental impact assessment (EIA) approval documents, waste collection and transportation scheduling records, client tender announcements, and customized marketing plan documents. Data update frequency aligns with business milestones: project-related data is updated when a bid is awarded, construction starts, or acceptance is completed; collection and transportation data is synchronized per operation cycles; marketing plan documents are revised as needed. The document structure includes fields such as project number, disposal category, disposal scale (units: tons, cubic meters), operation cycle, and compliance qualification requirements. Available formats include official PDF reports, Excel operational ledgers, and Word marketing proposals.
What constraints these characteristics impose on workflow orchestration
Decentralized data sources and diverse formats require the workflow to be configured with multi-source data access nodes, support parsing PDF EIA reports, Excel operational ledgers, and Word marketing proposals, and include built-in format conversion logic to unify field structures. The update frequencies of different data types vary significantly, so the workflow must support both scheduled triggering and event triggering startup modes. For example, synchronize collection and transportation data on a daily scheduling cycle, or automatically trigger marketing content generation when awarded project information is updated. Fields related to solid waste disposal have fixed units and compliance requirements, so the workflow must include a field verification step to confirm that the disposal scale unit complies with regulations and that required compliance qualification fields are present.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | PDF EIA reports for solid waste treatment often have a large number of pages; the default 120-second timeout often causes parsing failures. Extending the timeout to over 300 seconds covers most scenarios |
HTTP_REQUEST_TIMEOUT | 600 seconds | Some third-party qualification query interfaces and tender announcement interfaces have slow response times. A 300-second timeout will interrupt the workflow, so this setting must accommodate long response scenarios |
LOOP_MAX_ITERATIONS | 50–100 | The number of solid waste project documents uploaded in a single batch typically does not exceed 100. Limiting the number of loop iterations avoids unnecessary resource consumption |
WORKFLOW_TRIGGER_MODE | Scheduled triggering + Event triggering | Solid waste collection and transportation data is updated daily, requiring scheduled triggering; awarded project information updates require event triggering. Dual modes cover all full business scenarios |
GLOBAL_VAR_ASSIGN_FROM_API | Enabled | Project data for solid waste treatment must be retrieved from internal ledger APIs. The disposal_amount and waste_type fields returned by the interface must be directly assigned to global variables |
WX_MARKDOWN_RENDER_STRIP | Enabled | Technical parameters of solid waste marketing content do not need to be displayed on WeChat. Enabling this setting hides non-display Markdown syntax blocks |
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 case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: The workflow returns an
ETIMEDOUTerror with a 504 status code during execution. Cause: TheHTTP_REQUEST_TIMEOUTparameter was not adjusted, and the default 300-second timeout was retained, while the response time of solid waste-related qualification query interfaces exceeds this threshold. - Symptom: When extracting multiple documents in a loop, only the first N documents are processed, and no results are returned for subsequent documents. Cause: The
LOOP_MAX_ITERATIONSparameter was not set, or the value was too small to cover the actual number of uploaded documents. - Symptom: Marketing content sent via WeChat includes unformatted code blocks. Cause: The
WX_MARKDOWN_RENDER_STRIPconfiguration was not enabled, and technical parameter code blocks in solid waste proposals were not filtered.
How to confirm the configuration is complete
- Upload a solid waste EIA PDF with more than 100 pages, confirm that the workflow completes parsing within 600 seconds with no timeout errors.
- Configure a scheduled triggering task to synchronize that day's solid waste collection and transportation data, confirm that global variables correctly map the
disposal_amountfield returned by the interface. - Upload multiple solid waste project documents, confirm that the loop node processes each document in sequence with no omissions or duplicate executions.
- Configure a WeChat sending test, confirm that technical parameter blocks in Markdown-formatted marketing content are hidden.
