Hi Pankaj ,
Thanks.
Actually, before trying that way you mentioned, I reinstalled the latest OutsystemsReactiveTemplate (2.1.0)
OutsystemsMaps, SampleData, Chart ,UI are all the latest version. in this condition, I tried to install the latest OutsystemsReactiveTemplate.
But, I got this sort of error when uploading.

Then I'm done with upload&publish, and checked OutsystemsReactiveTemplate,
but it's missing TemplateExternalWebportal and ReactiveSampleUserApp and ReactiveWebapp.

My platFormServer version is 11.13.0. I wonder why this is happening and I'm not sure.
Does this look familiar with you?
Best regards,
