HI,

Can you please provide the type/version of the Catalyst Center (DNAC) you are using ?
also if you can upgrade your Radkit version to the latest one (1.8.0), then try to pull your DNAC devises.

waiting for ur replay !

[ufd]

We upgraded the Service to 1.8.0 and later to 1.8.0b8, and tried to delete the DNAC from device list, re-added and re-import from device, with exactly same result, giving us the output:  

'NoneType' object has no attribute 'strip'

DNAcenter Version 2.3.7.7-70047-CSCwn89323.SMU

We also tried to filter on tags while importing, and the correct number of devices is returned, so we do have connection to DNAC, but return data is broken?

And logs from Radkit Service:

Hi, Can you please provide the permission level of the Cat Center user(like observer or admin role?)

Thank you!

[ufd]

Admin role, actually SuperAdmin.
