Steps to Reproduce:

1. Choose an API that returns an object with boolean properties, for which there are GET and POST/PUT operations (so you can GET the object, then PUT it back with a minor change).
2. Build a GET request that returns the object in the body.
3. Build a PUT request that sends a matching object, where the values from the GET result are used. See example:

Example

{
  "subject": "{{user.response.body.subject}}",
  "username": "{{user.response.body.username}}",
  "email": "{{user.response.body.email}}",
  "firstName": "{{user.response.body.firstName}}",
  "lastName": "{{user.response.body.lastName}}",
  "isBlocked": true,
  "lockoutEnd": {{user.response.body.lockoutEnd}},
  "lockoutEnabled": {{user.response.body.lockoutEnabled}},
  "isDeleted": {{user.response.body.isDeleted}},
  "twoFactorEnabled": {{user.response.body.twoFactorEnabled}},
  "claims": {{user.response.body.claims}},
  "roles": {{user.response.body.roles}}
}

Result
The properties that are not strings enclosed in quotes are syntax-highlighted in red, which misled the idiot writing this issue into thinking the request was malformed and would not work. When I tried it and had problems, I mistakenly thought the syntax was wrong and spent a while working out what what the real problem was.
