Hi guys, I am having a hard time for a long time now. I keep having problems with updating one of my datasets. Sometimes I can update it within Desktop but in Service I always (with a few exceptions) I get a MYSQL Fatal Error message. I thought its because the Dataset is too big so I rebuilt it smaller (left out the costs and focused on the revenues...). Anyway. I still get the same Message:
{"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":"MySQL: Fatal error encountered during data read."}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourceKind","detail":{"type":1,"value":"MySql"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourcePath","detail":{"type":1,"value":"192.168.10.50</ip>;DWWProd"}},{"code":"Microsoft.Data.Mashup.ValueError.ErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft\.Data\.Mashup\.ValueError\.Message","detail":\{"type":1,"value":"Fatal error encountered during data read.<\/ccon>"}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"DataSource.Error"}}],"exceptionCulprit":1}}} Table: 02_Verkaufszeilen.
Can anyone give me a hint where to look? What could I have done wrong? Thanks!
yes, I use a gateway and I am fighting for a long time now. There was at least one gateway update.
Gatewayversion number is 3000.186.18
What's the MySQL driver version?
Do you use a gateway? Is it running 2.0.28 ?
