Problem with Pipeline Parameter in Mapper Snap

[jhagist]

I am using a mapper snap to extract data from a json schema. This is the code from the expression

{id:$id}.extend($.fieldValues.map (elem => [elem.id, elem.type, elem.value]))

What I want to do is place this in a pipeline parameter (so can change this equation from the config file).

I can’t figure out the expression syntax. Here is a screenshot of my latest failure. 🙁

Thanks for this. I am currently using the pipeline parameter to pass this information.

My question is really how to write the syntax.

I have put the function (that I need to variablize) into the Pipeline parameter _field1 but I can’t get it to run

you shouldn’t need parenthesis around the name. “_field1” should work.

When I try it without the parenthesis around the name. “_field1” All I get is the parameter as a string.

Snap,

Any ideas??
