Topic: MDB React 4.6.1 Carousel Error

cmykprnt pro asked 6 years ago


I just upgraded my MDB React Pro from 4.5 to 4.6.1. I copy and paste one your Carousel samples from the Carousel section and from the Ecommerce section. They both cause my application to crash with this error message on my screen: "Expected ref to be a function or a string." And in the console I can see this error message: [Error] The above error occurred in the <Carousel> component:     in Carousel (at LatestProducts.js:179)     in div     in Container (at LatestProducts.js:177)     in LatestProducts (created by Connect(LatestProducts))     in Connect(LatestProducts) (at EmployeeDashboard.js:12)     in div (at EmployeeDashboard.js:11)     in div (at EmployeeDashboard.js:10)     in div (at EmployeeDashboard.js:9)     in EmployeeDashboard (at Dashboard.js:23)     in div (at Dashboard.js:20)     in div (at Dashboard.js:19)     in Dashboard (created by Connect(Dashboard))     in Connect(Dashboard) (at requireAuth.js:27)     in Authenticate (created by Connect(Authenticate))     in Connect(Authenticate) (created by RouterContext)     in div (at StoreLayout.js:11)     in div (at StoreLayout.js:10)     in div (at StoreLayout.js:8)     in StoreLayout (created by RouterContext)     in div (at Layout.js:10)     in Layout (created by RouterContext)     in RouterContext (created by Router)     in Router (at index.js:19)     in Provider (at index.js:18)     in MuiThemeProvider (at index.js:17)     in App (at index.js:30) Consider adding an error boundary to your tree to customize error handling behavior. Visit https://fb.me/react-error-boundaries to learn more about error boundaries. logCapturedError (bundle.js:172763) captureError (bundle.js:173556) renderRoot (bundle.js:173407) performWorkOnRoot (bundle.js:174030) performWork (bundle.js:173983) requestWork (bundle.js:173894) scheduleWorkImpl (bundle.js:173748) enqueueSetState (bundle.js:169228) setState (bundle.js:217304) onStateChange (bundle.js:187636) onStateChange dispatch (bundle.js:219511) (anonymous function) (bundle.js:218737:7808) (anonymous function) (bundle.js:228995) promiseReactionJob So I don't know if I did something wrong (which I doubt) or it's a bug... I'd appreciate it if you could help me out. Thanks in advance!

Okay, I found the solution. For whoever has the same question, you need to make sure that your react & react-dom version is at least 16.4.1! Hope it helps.
