I came across this issue the other day while preparing for a Lunch & Learn for our support guys on Smart Access with Access Gateway. While I was clearing out some configurations in the AMC, this error popped up while trying to delete a web resourse. Not very informative.
The web resource was of type Citrix Web Interface 4.2 or later.
Running AAC 4.5 AAC450W004 (latest verion/patch), so thought I’d be ok.
After looking at my policies, filters to see if there was any references I found that the resource was still tied to the
XenApp farm at the AAC farm level.
AAC Farm -> Presentation Server Farms -> Web Interface
Once I unassociated the web resource from the XenApp farm I was able to delete it.
