Description

When SR (Script) tasks are retried, the init_sql loading process causes an exception due to null pointer exception when accessing the EngineTypeLabel. The method adjustErrorIndexForSetScenarios uses find().get which throws NoSuchElementException when the label is not present.

Steps to reproduce

1. Execute an SR task with init_sql configuration
2. Trigger a task retry scenario
3. The system throws an exception when trying to access EngineTypeLabel

Expected behavior

The system should handle the case when EngineTypeLabel is not present gracefully and continue execution without throwing exceptions.

Your environment

• Linkis version used: 1.18.0
• Environment name and version:
  • hadoop-3.3.4
  • hive-2.3.3
  • spark-2.4.3/3.3.0
  • scala-2.11.12/2.12.17
  • jdk 1.8.0_xxx

Anything else

The fix uses collectFirst instead of find().get to safely handle the case when EngineTypeLabel is not present, and adds null check for executionCode.
