I am trying to add a variable inside Additional data source expressions for document generator in Alfresco

I have this taskid variable and when i put it it doesnt work.

here is what works:

${transdataService.getData("DocName","55280"})} It works and

${transdataService.getData("DocName",${taskid})} doesnt and i get this error in logs:

Error parsing '${transdataService.getData("DocName",${taskid})}': lexical error at position 38, encountered invalid character '{', expected expression token at org.activiti.engine.impl.juel.Builder.build(Builder.java:97) at org.activiti.engine.impl.juel.TreeStore.get(TreeStore.java:61)

For passing variable inside expressions (${expression}), you do not require another expression tag as nested expressions are not allowed. To access a variable inside an expression, simply pass your variable literal as-is like ${transdataService.getData("DocName",taskid)}
