az resource update --name acusnpdsndweb06/config/web --resource-group azrg-tax-snd-m-dev --resource-type "Microsoft.Web/sites/config" --set properties.virtualApplications="[{\"physicalPath\":\"site\wwwroot\",\"preloadEnabled\":true,\"virtualDirectories\":null,\"virtualPath\":\"/\"},{\"physicalPath\":\"site\wwwroot\ConfigService\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/configService\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2020100516.2\",\"preloadEnabled\":true,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2020100516.2\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2020103014.2\",\"preloadEnabled\":true,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2020103014.2\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2020103018.1\",\"preloadEnabled\":true,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2020103018.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2020103021.1\",\"preloadEnabled\":true,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2020103021.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2020110421.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2020110421.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2020120707.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2020120707.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2020120810.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2020120810.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021020501.2\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021020501.2\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021021002.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021021002.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021033019.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021033019.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021033023.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021033023.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021033103.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021033103.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021033104.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021033104.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021040700.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021040700.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021040918.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021040918.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021061217.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021061217.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021072316.1\",\"preloadEnabled\":true,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021072316.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021072615.1\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021072615.1\"},{\"physicalPath\":\"site\wwwroot\FileManagerService\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerService\"},{\"physicalPath\":\"site\wwwroot\FMApiStoargeChangeTest\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/FMApiStoargeChangeTest\"},{\"physicalPath\":\"site\wwwroot\FileManagerApi2021072719.1\",\"preloadEnabled\":false\"virtualDirectories\":null,\"virtualPath\":\"/FileManagerApi2021072719.1\"}]"

Hi @Jayashree K C ,

Thanks for brining this to our attention. What version of CLI are you using? Is this a Linux or windows based app?have you tried updating your map pathing through the portal?

Based on this similar Github thread, az resource update is not designed to support updating the webapp config.

If you want to update the configuration of webapp, the following command should be executed:

az webapp config set --name {resource-name} -g {resource-group} --generic-configurations "{\"virtualApplications\":[{\"physicalPath\":\"site\wwwroot\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/\"},{\"physicalPath\":\"site\wwwroot\v2\flow-server\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/flow\"},{\"physicalPath\":\"site\wwwroot\v2\iris-server\",\"preloadEnabled\":false,\"virtualDirectories\":null,\"virtualPath\":\"/iris\"}]}"

Because only this command implements the function of Web Apps - Create Or Update Configuration.

It might be also helpful to check out this documentation regarding quoting best practices when using CLI.

Hope that helps.
