Working on Mule 3.9 to Mule 4.x migration work, API recieve json input payload as shown below, I am trying to check whether I have DFU string value existing in this array payload.sec_entities. Observed that in log statement condition check is working perfectly fine, see the log statement showing debug-8, debug-9, debug-10 below in Error logs. Question is it's not working same statement in when expression Can anyone suggest what is the issue with when expresion??
Tried with this, when expression fails:
<when expression="#[payload.sec_entities != null and payload.sec_entities contains 'DFU']">
Tried with this, even this when expression fails:
<when expression="#[%dw 2.0 output application/java --- payload.sec_entities != null and payload.sec_entities contains 'DFU' as String]">
Input payload:
{
"primary_entities": [
"DMDUNIT",
"LOC"
],
"sec_entities": [
"DFU",
"STOCK"
]
}
Code:
<flow name="Orchestrator-DFU-Flow">
<logger message="debug-8 expression check: payload.sec_entities: #[payload.sec_entities]"/>
<logger message="debug-9 expression check: payload.sec_entities not null check: #[payload.sec_entities != null]"/>
<logger message="debug-10 expression check: payload.sec_entities contains: #[payload.sec_entities contains 'DFU']"/>
