I have an angular 1.x webpart application which is built using the spfx 1.4 version. The webpart works in the modern sites pages but is not working on the classic site pages with custom master page. The error only occurs randomly i.e every 4th,5th time. After the error If I refresh again the webpart works.


Bootstrap module for web part WebPart.CsTaskBoardWebPart.g_76cddb14_eed9_4284_81a4_b8db3ff64e8c not of the correct type. Make sure to export your web part as 'export default WebPartName'.


The behavior is very confusing. anyone has faced this issue before?
