hello, I am trying to set up a simple raindrop to google sheet scenario  
I nearly get to what I want, but can not manage to find a solution for tags, that come as an array

As a first level scenario, I’d like to have the tags as a simple list, coma separated, so it can fit the a single gsheet cell.  
(I would be also be happy with a more structured string like a json pattern …)

I have a solution that worked at least once, on a single bundle with Tags

But I was not able to run this on the ten first bundles and I have this execution error.

I also have a surprise while investigating the problem, based on the UI, while composing the function in the gsheet module parameter screen :

I only see the first tag, not both. Is it standard ? or a clue that something is not working properly upstream ?

I suspect that this could come from cases where Tags is empty.  
I have two questions :

- would you have clues on how to fix this ?
- at evaluation time, does the error come sequentially (one bundle at a time) or at the batch level (all bundles are evaluated) ?
