XMLSyntaxError when using bbf yang models

[lvdh1]

When trying to generate a RPC to retrieve net-date rate from the bbf-fast-channel-performance-body.yang file I get a "HTTP request error"

I use the yang files available in : https://github.com/YangModels/yang/tree/master/standard/bbf

Looking at the logs it seems that there is an issue with the namespace : XMLSyntaxError: Namespace prefix bbf-fast on line is not defined, line 7, column 15

Restconf is able to generate the correct url, specifying all the namespaces , following namespace bbf-fast:line/bbf-fast:channel are in the path

The RPC that should be build is :

I can generate RPC up to the level of urn:bbf:yang:bbf-fastdsl, but 1 layer/container deeper I always get the namespace issues.

Any suggestion on where the root cause could be found ? Or what I can do to get more info for this issue.

Thanks

The issue was caused due to problems with utf-8 conversion when extracting the yang files from the BBF repo
