Hi community,

I have the following error during the run of the activity Deserialize JSON:

“Cannot create and populate list type Newtonsoft.Json.Linq.JToken. Path ‘responses’, line 2, position 16 uipath”

Until yesterday it worked, the only step I took was to migrate the project to a different remote machine.

Any ideas?

Thanks a lot

Hi @etasca ,

Could you maybe provide the json file, so that we could verify the json format from our end.

You could also validate the json string in the below link :

You should save it to a text file and post the file. The copy/paste is going to be difficult to work with.

I solved the issue.

The problem was related to the package version that I was using in the project.

In particular the dependence: Newtonsoft.Json that was in contrast with the one of Mail Activities Package.

Thanks a lot
