We have been having problems all day in building our interaction models and keep getting this 'Error: Failed building the interaction model.' response.
We have cleaned our cache, signed in and out, etc multiple times to no avail and are wondering if anybody else is seeing this problem too.
Interestingly, if we reduce the Sample Utterances from fifteen down to one we are sometimes able to save the model, but when we add in the rest of the utterances it keeps failing.
We are confident these fifteen utterances are not the problem as we have used them multiple times in multiple published Skills.
