   3 ```cpp
   4 class type_error : public exception;
   5 ```

   7 This exception is thrown in case of a type error; that is, a library function is executed on a JSON value whose type
   8 does not match the expected semantics.
   9
  10 Exceptions have ids 3xx (see [list of type errors](../../home/exceptions.md#type-errors)).
