## Describe the problem/error/question
I am creating a workflow: getting a list of my photography from Baserow with some multiple select field to describe the pictures as tags and running a custom chatGPT prompt before to re-inject the output to my database.
I have an issue with concatenating as a string all the multiple select value from baserow.
I tried by using the expression: {{$json[“Input_Tags_Location”].map(item => item.value).join(", ")}} but i get the invalid syntax
I will take the example of the Input_Tags_Location Object for which the expected output should be “Japan, Tokyo, Shibuya”
## What is the error message (if any)?
