Deserialize JSON error

Help

I’m trying to deserialize JSON from an API. but I’m getting the below error. I’ve seen similar issues that were resolved by re-booting and re-installing. I have tried both and the problem persists. Any ideas?

Can you post in the shared thread in my previous post. If they have some idea about this.

what are you trying to parse exactly in JSON? can you post the input/or a part of it?

Make sure you have the UiPath.Web.Activities package installed and up to date.

All sorted now thanks. I had the variable set to the wrong type. Rookie error :roll_eyes:
