Describe the bug
Mockoon is generating an error when using setVar within an #each block. This behavior appears to be similar to #429.
Example error message: Error while serving the content: Cannot create property 'testVar' on string '1'

To Reproduce
This is a sample Response Body that results in this error. This Response will work if setVar is removed.

{
  {{#each (split '1 2 3')}}
  {{setVar 'testVar' '4'}}
    "test": {{this}}
  {{/each}}
}
