Change to FeatureSharingDraft tags property after upgrade ArcGIS Pro to 3.4

Question

I just upgraded my desktop machine to ArcGIS Pro 3.4 from 3.3.x, and noticed a change to the FeatureSharingDraft class tags property.  After updating my cloned python environment, I was getting an error in one of my python scripts on the last line in this snippet:

sharing_draft = mp.getWebLayerSharingDraft("HOSTING_SERVER", "FEATURE", sd_fs_name)
sharing_draft.summary = "my summary"
sharing_draft.tags = ["tag1", "tag2"]
sharing_draft.exportToSDDraft(sddraft)

The error was: Error exporting SD Draft: 'list' object has no attribute '_validateParameters'

When Pro 3.3.x was installed this error did not occur.  Turns out it was the tags property - it cannot be a list, it must be a string with tags separated by a comma or semi-colon.  Its strange that this property was always specified in the documentation to be a string, but I was using a list without error.

Just posting this in case anyone else has a similar issue.

This actually breaks backwards compatibility, because tags are listed in an array in the item JSON, so when migrating items with arcpy, it will fail.

So you may find this interesting @Jamie_Leitch_CNF  - when I tried to overwrite my layer like I detailed above, the

arcpy.UploadServiceDefinition_server('C:/ArcProProjects3x/PortalUpdates/Transportation/' + lyr.name + '.sd', 'My Hosted Services', "","","","","","OVERRIDE_DEFINITION","SHARE_ONLINE","PUBLIC",
                                                     "SHARE_ORGANIZATION","Transportation Layers Group")

failed with five 9's - 99999 something unexpected....

Turns out that where I am specifying the group to be shared with, "Transportation Layers Group" in my case  I now need to specify it as a list:

["Transportation Layers Group" ]

Once I did that, the Upload Service Definition method works

So basically like I have the tags parameter currently formatted.  Thanks @Jamie_Leitch_CNF
