# horrible hack but no easy way to resolve this
# requires preventing request parameters being compiled to snakeCase
# in this dependency: https://github.com/googleapis/gapic-generator-typescript/blob/master/templates/typescript_gapic/src/%24version/%24service_client.ts.njk
# i will personally buy a beer to whoever can solve this, good luck.
