Improve enrichment process for rules, transactions, and graphs

[coderabbitai]

Background

Currently, the enrichment process for various entities (rules, transactions, and graphs) lacks proper null checks and error handling when mapping related entities.

Areas Affected

1. Rules enrichment

   • Label mapping in rules needs proper null checks
   • Error handling for missing labels needed

2. Transactions enrichment

   • Similar issues may exist with related entity mappings
   • Need to review and improve error handling

3. Graphs enrichment

   • Review and improve entity mapping process
   • Add proper null checks and error handling

Proposed Solution

Implement a consistent approach across all enrichment processes to:

• Add proper null checks when mapping related entities
• Include error logging for missing entities
• Filter out null values from the final result
• Consider adding validation at the data layer

Note: This improvement will help prevent runtime errors and provide better debugging information when related entities are missing.
