How to cite entries in an array of JSON (position of entries is not fixed)

Hi @shuo,

In this situation you can use .find() function.

Here is one simple expression.
Check Null-safe Access in the Mapper.
$entity.entries.find(f => f.get('Pipeline') == 'Pipeline_Failed').Numbers

If for example there’s not ‘Pipeline_Failed’ when you validate/execute then will return you a null.

Viktor
