Awesome @VelinGeorgiev! I'll have a look shortly 👍

According to the command help, I should be able to pass site- or server-relative URL of the folder where I want to set the property bag value. If I try the following setup:

spo propertybag set --webUrl https://contoso.sharepoint.com/sites/team-b --key myprop --value myval --folder '/sites/team-b/Shared Documents'

it fails with a File Not Found. error.

Using:

spo propertybag set --webUrl https://contoso.sharepoint.com/sites/team-b --key myprop --value myval --folder 'Shared Documents'

works just fine. So it seems that the command accepts a site-relative folder URL but not a server-relative one. Could you please double check @VelinGeorgiev?

[VelinGeorgiev]

Hey, @waldekmastykarz can we keep to site relative url and change the option description? The option says --folder and makes sense to be a folder within the site. The way I implemented it is exactly how PnP PowerShell works. Perhaps we can stay consistent and leave it to site relative folder path. What do you think?

Making it consider site or server relative folder path will add additional checks on our end to make it execute the correct XML request.

[waldekmastykarz]

Makes perfect sense to keep it site-relative. Let's adjust the docs 👍

[VelinGeorgiev]

Server relative removed form the description.

Well done sir! 👏

Merged manually 👍
