the reviews doesn’t shown in API request

Hi,
I have purchased fluxstore woocommerce which supposed to be compatible with your plugin but unfortunately the reviews doesn’t appear in the app
below are the response from their side :
“Hi mate,

I have investigated this issue, please take a look at this picture https://share.cleanshot.com/bTDdRmP2

The image link of this review item which contains a boolean value, but it should be a String value or empty because the app parses this item to String, if can not parse, it will throw an exception and does not show any review.

So please double-check your server

Regards,
Loc.”

is there any recommended setting that will make this work ?
