----------------------------------
Summary: LookUpRecord record path evaluation is "breaking" the

Project: Apache NiFi

Input JSON generated by GenerateFlowFile processor looks like this (actually I
just added a currencies array under each record in addition to the "Record
Update Strategy - Replace Existing Values" example here
[https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.15.0/org.apache.nifi.processors.standard.LookupRecord/additionalDetails.html).]
*Note:* for the first record currencies array is empty.
{code:java}
[
{
"locales": [
{
"region": "FR",
"language": "fr"
}, {
"region": "US",
"language": "en"
}
],
"currencies": []
}, {
"locales": [
{
"region": "CA",
"language": "fr"
},
{
"region": "JP",
"language": "ja"
}
],
"currencies": [
{
"currency": "CAD"
}, {
"currency": "JPY"
}
]
}
]{code}
SimpleKeyValueLookUp service contains the following values:

LookUpRecord processor is configured as follows:
!image-2022-02-11-12-30-53-134.png!
Once I execute the LookUpRecord processor for the flow file, language look up
works fine, but the look up for currencies and regions look up does not work.

*Note:* in case the 1st currencies array is not empty but contains \{
"currency": "EUR" }, \{ "currency": "USD" }, all look up works fine. But a
missing data seems to break the next evaluation of the record path.
Please find the template for reproducing the issue enclosed.
Thank you.
