[Bug]: cancelExecution does not throw error for invalid executionId

[SSJane]

Bug Description

When calling chainService.cancelExecution with an invalid executionId, the function currently returns undefined instead of rejecting the promise. This causes test cases that expect an error to fail

Steps to Reproduce

1.Call cancelExecution with a non-existing execution ID:

await chainService.cancelExecution("invalid-id");

2.Observe that the promise resolves instead of rejecting.

Expected Behavior

The function should throw an error:

Error: Execution not found

Actual Behavior

The function silently returns undefined.
