Custom Connector Creation
I am attempting to create a custom connector for an ODBC SQL Anywhere server. I used the provided example for a custom ODBC connector and attempted to modify it.
When I test it, I repeatedly get the same error:
I am uncertain how to troubleshoot this bug. If anyone has created Custom Connectors and can point me in the right direction, that would be appreciated. Thanks.
I ended up starting over with a fresh copy of the sample code from Microsoft (https://github.com/microsoft/DataConnectors/tree/master/samples/ODBC) and was able to get it working.

Have attempted to troubleshoot this issue myself. What I have ascertained is that it is related to the options used in the ODBC.DataSource function. When I comment out some of the options from the ODBC example code, this error stops appearing. However, at that point, Power BI fails to query fold my data source and I can't do anything except list the values in a table. Can't do very much in the way of filtering or using DAX functions.
I would assume something in this set of options needs to be set correctly based on my driver. While I can find documentation on these options, I am uncertain what resources to peruse in terms of the ODBC driver I am using to figure out which settings are necessary to make the Direct Query functional in Power BI.
Any assistance would be appreciated.
Hi Anonymous ,
I know few about Custom Connector. I may not be able to help you in this regard.
But for Direct Query, there are some limitations of data transformations. And to my knowledge, there is no workaround unless connection mode is switched to Import.

Hi Anonymous ,
Glad to hear that. Could you share the sample code with us? We are curious about that.😀
And please accept it as solution to your question so that people who may have the same question can get the solution directly.
