json: cannot unmarshal bool into Go value of type string

[0-wiz-0]

So this might be a problem apisprout (danielgtaylor/apisprout#81), but it could be in the Specs - the error is quite long. Perhaps someone has some insight.

Reproducer:

git clone https://github.com/jdegre/5GC_APIs
# commit da92f21c0e6b2b112f79670eb61cf9f7617bba22 as of right now
cd 5GC_APIs
apisprout TS32291_Nchf_ConvergedCharging.yaml

gives the attached long error, ending with:

Error while unmarshalling property 'required' (*[]string): json: cannot unmarshal bool into Go value of type string
