Hi Ole, Currently I have below issue as describe in your https://gerrit.fd.io/r/#/c/19389/,
""" An IPv4 or IPv6 address was previously defined like: ``` u8 is_ip6; u8 address[16]; ``` Which made it hard for language bindings to represent the address as anything but a byte string. The new explicit address types are shown above. """ I bumped into ip address defined like above, then what is the correct way to pass ip address to python api ? I tried below way, but it seems that is not corrent, vip_addr = ''.join(list(inet_pton(AF_INET, '90.1.2.1'))) pass `vip_addr` to a python api that need ip address, I can not get the correct result.

You can enable logging in the Python mode that gives quite a bit of information. Feel free to add to that btw. There is also API tracing on the VPP side you can enable. And of course you can run both the Python side and the VPP side in debuggers. But yes, any suggestions for how debuggability of developing new API messages are welcome.
