Expected Behavior

groups/{groupId}/?Action=generateInvitationLink, return invitationLink

It seems this error occurs in the router. Can you get the body of the request?
Or do you have any idea how to resolve this problem?

@hitohata
Yes, I found c.req.json(), occurred the error because it doesn't have body data when the Action is generateInvitationLink. I'll fix it soon

[hitohata]

OK. I've made sense. I didn't know if the body was not provided, this error would occur. I feel like I really learned something today. Thank you.
