Validation error on simple jsonpath on install

[Hooghof]

On these simple expressions in a setheaders a validation error arises on install:

${empty(String)}${jsonpath($.GeneralJournalEntryLines.[].GLAccountCode)}
result=${jsonpath($.GeneralJournalEntryLines.[].Description)}

Validation error after install: Cannot invoke "org.apache.camel.TypeConverter.convertTo(java.lang.Class, Object)" because the return value of "org.apache.camel.CamelContext.getTypeConverter()" is null
Cannot invoke "org.apache.camel.TypeConverter.convertTo(java.lang.Class, Object)" because the return value of "org.apache.camel.CamelContext.getTypeConverter()" is null

Camel 4.10.9 allows this simple expression.
Question: is it not allowed in Camel 4.22 anymore?

Short answer is I don't know. It seems that every jsonpath fails in validation, because even:

${jsonpath($.foo)}

Fails. I created a ticket for Camel:
