It looks like there is an issue with using date_settings as the econ name. We should be able to handle any combination of date-settings on our end, and we will fix it.
In the meantime, would you mind using dates rather than date_settings?
Here are some of those keys that should work for you
'capex',
'dates',
'depreciation',
'differentials',
'emission',
'escalation',
'expenses',
'fluid_model',
'general_options',
'ownership_reversion', // we also accept ownershipandreversion, or ownershipreversion
'pricing',
'production_taxes',
'production_vs_fit', // This is actual-forecast we also accept actualforecast, or actualorforecast
'reserves_category',
'risking',
'stream_properties',
is there a way to assign forecasts using the API?
As of right now, we only assign econ models. If there is a need to be able to assign forecasts, I suggest you reach out to your account manager at ComboCurve and request this as a new API feature so that we can get it on our roadmap.
