Description

When using Expression Language it was possible to lookup parameters from ContextParameters and variables from VariableRegistry. Examples:

${ literal('#{Tenant-Testing-HOST1}'):evaluateELString() }
${ literal('${Testvar}'):evaluateELString() }

Both were working in NiFi 1.18.0. Now with NiFi version 1.21.0 this stopped working for ContextParameters and only lookups of varaibles are working. Please see the attached template with an example flow.
