mORMot Open Source

I just installed mORMot2 and compile mORMot2test with lazarus4.6 FPC 3.2.2 on window10 pass but it's running an error.

1.2. Core process:
  - RTTI: 1,653 assertions passed  646us
  - Data structures: 13,964,844 assertions passed  159.94ms
  - Url encoding: 3,264 assertions passed  844us
  - Encode decode JSON: 564,778 assertions passed  100.61ms
  - JSON benchmark: no assertion  1.82ms
  - Wiki markdown to html: 817 assertions passed  320us
  - Variants: 167 assertions passed  122us
  - Mustache renderer: 190 assertions passed  3.25ms

and Debugger Exception Notification
raised exception class 'ESynVariant' with message: TDocVariant.DispInvoke: invalid (1)

Where do I need to fix it?
