TypeError: (0 , zt.isPlainObject) is not a function

Hi all!

I have had a problem for 5 days. It was everything fine before last friday and I dont know what was changed after. I constantly get an error message from Swagger Editor when I am trying to send a request with a body message. I have no idea what is the problem but it seems any body message couses this type of error on the site and the request will be never sent actually (I get only an infinit "Loading" marker).
