I think this might be an API error, documentation issue perhaps or between the computer and the chair.

I cannot seem to get this to work using REST Call: https://docs.microsoft.com/en-us/sharepoint/dev/apis/alm-api-for-spfx-add-ins

Section: Install solution package from tenant app catalog to SharePoint site

My script works because I can call other endpoints i.e. /_api/web ok.

The user account I am using is set to Targeted Release, I assume these APIs are available in tenants. Paul

It is not working for me either, i get this Error : Install-PnPApp : {"odata.error":{"code":"-1, System.ServiceModel.ProtocolException","message":{"lang":"en-US","value":"The remote server returned an unexpected response: (405) Method Not Allowed."}}}.

I am also having the same issue: Install-PnPApp : {"odata.error":{"code":"-1, System.ServiceModel.ProtocolException","message":{"lang":"en-US","value":"The remote server returned an unexpected response: (405) Method Not Allowed."}}}.

Is there an alternate way using ALM REST APIs?

I'm having the same issue installing an app on a site where the app already exists in the app catalog. Has anyone been able to resolve or work around the issue?

[GitHubO365]

I had the same issue. What I did was export a site template on one SP Online tenant and an import on another. I thought, since the same app is installed in both environments it would have the same ID. This doesn't seem to be the case. The ID is different between tenants. If you are having the same issue you can use Get-PnPApp to find all available apps and their IDs.

I am using SharePointPnPPowerShellOnline version 3.26.2010.0
