Error when refreshing dataset connected to dataflow

Hi all,

Since this morning I'm getting the following error. This exact dataflow has worked for several months before. Nothing has changed in the dataflow itself. This is the only report getting this error. Other reports that are using the exact same dataflow are working correctly.

How to solve this?

Data source error: {"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"Access token has expired, resubmit with a new access token"}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.Error","detail":{"type":1,"value":"error \"Microsoft.Mashup.Engine1.Runtime.ValueException: [Expression.Error] The field 'pbi.error' of the record wasn't found.#(cr)#(lf) at Microsoft.Mashup.Engine1.Language.ValueCreator.CreateValueForThrow(IThrowExpression throwExpr)#(cr)#(lf) at Microsoft.Mashup.Engine1.Language.ValueCreator.<>c__DisplayClass23_0.<CreateValueForRecord>b__0(Int32 index)#(cr)#(lf) at Microsoft.Mashup.Engine1.Runtime.RecordValue.DemandRecordValue.get_Item(Int32 index)#(cr)#(lf) at Microsoft.Data.Mashup.ProviderCommon.MashupResource.TryGetValue(Func`1 getValue, IValue& value, String& errorMessage)#(cr)#(lf)Record\""}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"TokenExpired"}},{"code":"Microsoft.Data.Mashup.ValueError.RequestId","detail":{"type":1,"value":"1bb8bf44-9923-4a05-bcd4-f1f6fcf22917"}},{"code":"Microsoft.Data.Mashup.ValueError.RequestUrl","detail":{"type":1,"value":"https://api.powerbi.com/powerbi/globalservice/v201606/clusterdetails"}}],"exceptionCulprit":1}}} Table: DimDate.
