Error	Description
`CampaignBudgetError.CANNOT_UPDATE_CAMPAIGN_BUDGET_TO_IMPLICITLY_SHARED`	Indicates that you tried to set the `explicitly_shared` field of a budget from `true` to `false` in an `update` operation. Once a budget is explicitly shared (`explicitly_shared = true`), you cannot change `explicitly_shared` back to `false`.
`ResourceCountLimitExceededError.ACCOUNT_LIMIT`	Indicates you've reached the maximum number of budgets in an account.
`CampaignError.CAMPAIGN_CANNOT_USE_SHARED_BUDGET`	The campaign to which you're trying to add the budget is using campaign experiments, and the budget is already being used by another campaign.
`CampaignBudgetError.CAMPAIGN_BUDGET_IN_USE`	You're trying to remove a budget associated with one or more active or paused campaigns.
