Uploading Apache certificate chain

Trying to implement smart card auth for the big-ip configuration utility, but unable to upload the cert chain via the ui or cli. Receive the following error:

 

Values (/parition/name) specified for Certificate Bundle Entity (/partition......) foreign key index (certificate_file_object_FK) do not point to an item that exists in the database.

 

I've seen references to this error and a bug in 11.5, however this is 12.1.2 and also having the problem with 13.0

 

I've uploaded the bundle elsewhere and it's fine. Does anybody know if the bug is still outstanding or any work arounds?

 

Appreciated.
