The linking of an ad account to a Business Manager section in the Developer Dashboard's ads configuration page fails. Specifically, the GraphQL mutation OCDevManageApplicationAdsLinkToBusinessManagerSectionMutation returns an error code 1357006 with the message "We're having trouble completing your request. Please try again." This error originates in Relay's GraphQL network layer, within the RelayGraphQLRequestUtils.createErrorFromPayload function. As a result, the ad account linking flow to Business Manager cannot be completed.
