@zhangKunUserGit I have the same issue, wonder if you use storybook-readme ?

for me it started happening suddenly (I didn't update any dependencies), error is disappeared if do not use storybook-readme. So I am not quite sure what the issue is, need to look further.

@zhangKunUserGit also as an option, you can lock to storybook version 5.2.8

You could try adding an empty options object to addParameters; that worked around it for me. (It's still a bug though.)

addParameters({
  // ... whatever you had before
  options: {}
});

looks like storybook-readme needs to update its dependencies
