I am trying to upload a app generate with SharePoint Framework to the App Catalog of my SharePoint, but when I upload it, it don't recognize how a valid package and I can't add this app to my developer site where I upload the workbench. I don't see the app in the list of available apps for add.
I tried do all of the SharePoint framework guide but I don't accomplish upload a valid app.
Too, I tried to upload here the workbench but it don't work.
I hope your help for can deploy the app.
Maybe you have to try to do things again. In the guide, you should
Open package-solution.json from the config folder. The package-solution.json file defines the package metadata as shown in the following code:
{
"solution": {
"name": "helloworld-webpart-client-side-solution",
"id": "ed83e452-2286-4ea0-8f98-c79d257acea5",
"version": "1.0.0.0"
},
"paths": {
"zippedPackage": "helloworld-webpart.spapp"
}
}
When this is done, run the gulp command
gulp package-solution
The command will create the package in the sharepoint folder: helloworld-webpart.spapp
So far so good, next
Upload or drag and drop the helloworld-webpart.spapp to the App Catalog.
... and click Deploy.
When I do this, I get a ProductID on my dev-tenant App site, but from your screenshot I can tell that there is no ProductID, and maybe that's where things fail?
Another option, which you might have missed, is to install Drop 4 and upgrade your web parts? I had these issues doing a demo, and later on when I upgraded to Drop 4, everything worked like a charm. See Release Notes Drop 4 and MDL2 on how to upgrade your apps.
Make sure you are using a Developer Tenant, not a developer site.
Your solution name might be too long (in "package-solution.json"), the limit is 64 characters. Keep it <= 64 characters.
I had a similar problem here.
