[RDS] type object 'Instance' has no attribute '_get_microversion_for_list'

[eumel8]

I tried a openstack rds instance list which failed with

type object 'Instance' has no attribute '_get_microversion_for_list'

Traceback (most recent call last):

Just wondering why it worked yesterday.

[lego963]

@eumel8 can you try to downgrade openstacksdk==0.61.0

I suppose that it can be a problem

[eumel8]

@lego963 result: No module named 'openstack.common'

otcextensions==0.26.3 works, otcextensions==0.27.0 is also broken (with openstacksdk==0.61.0)

[pdstefan]

Same behavior with openstack --os-cloud otc cce cluster show.

Downgrading openstacksdk to 0.61.0 fixes the warning but I get the following warning:

[lego963]

@pdstefan can you pin python-openstackclient==5.8.0?

[pdstefan]

python-openstackclient==5.8.0

Not good. Same behavior as previously mentioned (Configured hook otcextensions.sdk:load cannot be executed: No module named 'openstack.common')

After playing around with versions, I got back the original behavior:

[anton-sidelnikov]

latest stable version is otcextensions==0.26.3 with openstacksdk==0.61.0, newest versions of sdk has bunch of changes which brakes the backward compatibility. Will try to update

[anton-sidelnikov]

@eumel8 fun fact that's we already fixed this on 0.99.0 version of sdk (https://github.com/opentelekomcloud/python-otcextensions/pull/309), and on 0.101.0 it again reproducible

[anton-sidelnikov]

@pdstefan @eumel8 try new release with latest's versions, should work

[eumel8]

thx @anton-sidelnikov Are you sure this release is uploaded to pypi? The release job is marked with post_failure and I couldn't found it in the repo. https://zuul.otc-service.com/t/eco/builds?job_name=release-python&project=opentelekomcloud/python-otcextensions

[gtema]

In few minutes will be uploaded. We switched to Ansible 6 and it has bit different behavior for shebangs in the modules

[gtema]

https://pypi.org/project/otcextensions/0.28.2/

[eumel8]

yes , worked now:

otcextensions==0.28.2
openstacksdk==0.101.0

many thx @anton-sidelnikov @gtema

[pdstefan]
