Hello. I am using the JMWE "Set Entity Property value" post-function and would like to pull a value from a project-level entity property. The value of the project entity property that I am trying to use has only a string value. (No sub-entities or lists)

I have tried:
{{ project.properties."testproperty" }}
{{ project.properties["testproperty"] }}
{{ project. Properties.testproperty }}
{{ project | projectProperty("testproperty") }}
Any ideas on how to pull a project property using Nunjucks?
