After generating the new javascript-client, the v2 endpoint came back like this EndpointResourceV2$V2_getEndpoints vs the v1 that looks like  EndpointResource$V1_getEndpoints. It seems the V2$V2 is an operation ID and while this is not blocking any work let's fix it as the openapi specs are used/seen by our customers

for more context – See v2 openapi.json file and search for getEndpoint. Notice the EndpointResourceV2$V2_getEndpoints.
Compare with v1 openapi.json file and search for getEndpoint. Notice EndpointResource$V1_getEndpoints.
