"msg": "'dict object' has no attribute 'iteritems'"

[eawain]

Hi been running into issues with some of the roles running ansible 2.9.4 and python 3.6.9
From what I've googled it could be an issue with python 3.0 . I'll try and load an old python 2 instance just for testing to confirm.

Some modules like the snmp module work fine but a straight forward code sample to set hostname of switch fails like this.For time being I've fallen back to the module but I much prefer using roles as it looks cleaner. I've hit some weird idempotentency issues with the module when paired to lists.

dellos_system:
hostname: switcha
