Error compiling IP-MIB

Problem:
When trying to Generate Data Collection for IP-MIB.mib in GUI SNMP MIB Compiler I get this error:

I have no idea what that means and how to fix this.

Expected outcome:
Data collection to be generated

OpenNMS version:
Horizon 29.0.9

Hi.
I have faced the same problem with another MIB.

This happens when trying to create Data collections in the GUI, so I wonder if it also happens when one configure it using the configuration files SnmpCollector (opennms.com)

But didn’t had the time yet to try it.

But, by what is stated here, maybe it is not supported and we have to change IpAddress use by string on the MIB …
Data Types (opennms.com)

Anyone from the developing team can confirm if ipaddress is not supported at all by the DataCollection process ?

Since IpAddress is defined in SNMPv2-SMI that is compiled, I was expecting it to be usable.

Best regards,
Ricardo

While IpAddress is part of the RFC specs for MIBs, we need the type set to STRING for datacollection definitions. (As stated in that data type document linked above)
