Uncaught TypeError: Cannot read property 'setTargetNode' of undefined

I am getting this issue when updating new version of "@coreui/react": "^2.0.8", 2.0.8 is working fine.
So apps breaking because of:
Warning: Failed context type: The context isOpen is marked as required in DropdownToggle, but its value is undefined.
in DropdownToggle
in li (created by Dropdown)
in Manager (created by Dropdown)
in Dropdown (created by AppHeaderDropdown)
in AppHeaderDropdown

Hi @Harish-singh33

in src/containers/DefaultLayout/DefaultHeader.js change

<AppHeaderDropdown direction="down">

to

<UncontrolledDropdown nav direction="down">

UncontrolledDropdown does not require isOpen nor toggle props to work.

Hi,

I got the same problem and I fixed that by do not update react, so I use tilde ("~") instead of caret ("^" ) before the coreui/react version number.

e.g:

"@coreui/react": "^2.0.8" ->  "@coreui/react": "~2.0.8"

I solved it thanks to this comment -> https://stackoverflow.com/a/57903640, updating the reactstrap version from "7.1.0" to "8.4.1"

"reactstrap": "^7.1.0" ->  "reactstrap": "^8.4.1"
