Sharepoint - SPFX not showing webpart properties in modern page
I am not sure what was the actual issue. I uninstalled the Gulp, yo, Microsoft SharePoint generator. and installed again. and generated a new application which started working. Earlier my SPFX version was 1.7.0 now it is 1.7.1. Hoping that there was some issue with the SPFX package version or other packages related to this application.
