Trying to use kikit 1.6.0 on 8.0.7 throws error

[bipsendk]

Trying to use kikit to panelize a PCB - but when running it, I get an information message:

ufunc ‘create_collection’ not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule “Safe”

Any idea what causes it ?

Kikit panelize command used:

kikit panelize^
    --layout "hspace: 3mm; vspace: 3mm; vbackbone: 3mm; rows: 2; vbonecut: False; baketext: False" ^
    --tabs "type: fixed; vwidth: 5mm; vcount: 3; hcount: 0" ^

If you have a problem with a plug-in, you are likely to get a more helpful response from the plug-in author - so check the KiKit website first.
