primary-ip list -o json causes crash

[emrul]

I am using the latest release, v1.30.1 and this is my output:

❯ hcloud primary-ip list -o json
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x149299d]

Note, if I run without -o json it works fine:

❯ hcloud primary-ip list
