CampaignPerformanceReportRequest stopped working

Hi there,

Since a few days we're seeing errors when trying to fetch data with a CampaignPerformanceReportRequest: https://video2.skills-academy.com/en-us/advertising/reporting-service/campaignperformancereportrequest?view=bingads-13

We've first noticed it stopped working the 6th of Jan.

For reference, the wsdl: https://reporting.api.bingads.microsoft.com/Api/Advertiser/Reporting/v13/ReportingService.svc?singleWsdl

And the report request we send along to SubmitGenerateReport:

ReportRequest: {    
	ExcludeReportFooter: true,    
	ExcludeReportHeader: true,    
	FormatVersion: '2.0',    
	Aggregation: 'Summary',    
	Columns: [{        
		CampaignPerformanceReportColumn: ['Conversions', 'Clicks', 'CampaignId'],    
	}],    
	Filter: {},    
	Scope: {        
		Campaigns: {            
			CampaignReportScope: [                
				{ AccountId: '<redacted>', CampaignId: '<redacted>' },                
				{ AccountId: '<redacted>', CampaignId: '<redacted>' },                
				{ AccountId: '<redacted>', CampaignId: '<redacted>' },                
				{ AccountId: '<redacted>', CampaignId: '<redacted>' },            
			],        
		},    
	},    
	Time: {        
		CustomDateRangeEnd: { Day: '09', Month: '01', Year: '2024' },        
		CustomDateRangeStart: { Day: '11', Month: '12', Year: '2023' },    
	},   
	attributes: { 'xsi:type': 'tns:CampaignPerformanceReportRequest' },
}

Anyone else having this issue as well by any chance?
