I am trying to figure out how to deploy two versions of an SPFx Webpart to the App Catalogue. We need one for production and one for development.
What I have tried so far:
- Modifying the ID in the *.manifest.json file
- Modifying the ID in the package-solution.json file
- Changing the name (as well as the filename) of the solution
Each time I deploy the production version, SharePoint comes up with the following error:
SharePoint SPFx Component ID {0} exists in solution {1} already.
Edit: Following some advice in this post, it still makes no difference.
Thanks for your help.
