Hi @TonkatsuRamen 

For us to have more info, post screenshots of the DATA IN tab so we can see how the Formatter step is configured.

Also, post screenshots showing how the original data is structured from the previous step.

You may be trying to pass in an array of items.

You may have to try using this Zap action first: Formatter > Utilities > Line Items to Text

That will flatten the array into a string of text.

I try this solution (Formatter > Utilities > Line Items to Text) and it work. Thank you

Thanks so much for circling back in here @TonkatsuRamen to confirm that worked for you. And thank you @Troy Tessalone for the suggestion. The Community greatly appreciates it!  🧡

Seems like things are sorted for the moment but please do reach out in the Community again if you get stuck again in future.

Until then, happy Zapping!
