TypeError: MyStaticMibScalarInstance.getValue() got an unexpected keyword argument 'snmpEngine'

[miguel-slc]

Expected behavior

When running the example available in the documentation (agent-side-mib-implementations#agent-side-mib-implementations), I should be able to retrieve the value defined in the function getValue (class MyStaticMibScalarInstance)

Actual behavior

When running the example, I get the following error:
TypeError: MyStaticMibScalarInstance.getValue() got an unexpected keyword argument 'snmpEngine'

Detailed steps

Once the script is running, I performed the following command:
snmpget -v 2c -c public 127.0.0.1:20161 1.3.6.5.1.0
