I have added import Plupload from '../Components/upload/Plupload'
and I get this error:
Plupload.js:148 Uncaught TypeError: window.plupload.Uploader is not a constructor at Plupload.initUploader (Plupload.js:148) at Plupload.runUploader (Plupload.js:37) at Plupload.componentDidMount (Plupload.js:120) at commitLifeCycles (plupload.full.min.js:29) at commitLayoutEffects (react-dom.development.js:303) at HTMLUnknownElement.callCallback (lodash.js:7012) at Object.invokeGuardedCallbackDev (lodash.js:7062) at invokeGuardedCallback (lodash.js:7120) at commitRootImpl (react-dom.development.js:36) at unstable_runWithPriority (react-dom.development.js:11685) at runWithPriority$1 (lodash.js:14168) at commitRoot (webpackHotDevClient.js:164) at performSyncWorkOnRoot (pubsub.js:229) at lodash.js:14219 at unstable_runWithPriority (react-dom.development.js:11685) at runWithPriority$1 (lodash.js:14168) at flushSyncCallbackQueueImpl (lodash.js:14214) at flushSyncCallbackQueue (lodash.js:14203) at flushPassiveEffectsImpl (react-dom.development.js:491) at unstable_runWithPriority (react-dom.development.js:11685) at runWithPriority$1 (lodash.js:14168) at flushPassiveEffects (react-dom.development.js:322) at react-dom.development.js:204 at workLoop (react-dom.development.js:11635) at flushWork (react-dom.development.js:11607) at MessagePort.performWorkUntilDeadline (react-dom.development.js:11369)
