Error from parameterized info links

hi,

 

I have datatable formed of 3 parameterized info links - IL1, IL2, IL3. Input is either provided by document property or expression.

 

Data table is  formed from IL1 and then columns are inserted from IL2 and IL3 and each of them left joined with rows from IL1.

 

Information link gets refreshed sometimes with right data otherwise Im gettting the below error.

 

Failed to execute data query
  at Spotfire.Dxp.Data.Import.InformationLinkDataSourceConnection.ExecuteQueryCore2()
  at Spotfire.Dxp.Data.DataSourceConnection.ExecuteQuery2()

  at Spotfire.Dxp.Data.OnDemand.InformationLinkFunctionExecutor.d__0.MoveNext()
  at Spotfire.Dxp.Data.DataFunctions.DataFunctionExecutorService.d__6.MoveNext()

 

Any suggestions to resolve this error
