Valid json body through Custom Action

Hello, I am making an integration with a 3rd party through Custom Action, but when trying to Run Request, an error appears stating that I should enter a valid JSON body, I already validated the json here: JSON Formatter & Validator an shows no error. Any advice on what should I change? Thanks. (I include images)

Try deleting all spaces. If you did any copy and pasting you can also retype the " "

Thanks for the advice, for some reason whenever I try to edit the last " it cuts part of the text. I am using Firefox since it is a better browser for Custom Action, but this feature is having trouble when editing…

Did you figure out the text disappearing when typing in the field? I also use Firefox and have the same issue.

Hello Bernard, not yet but will let you know
