Hey All,
Getting the following error when (auto) refresh is triggered:
Last refresh failed: Wed Jan 09 2019 06:15:24 GMT+1100 (AUS Eastern Daylight Time)
Cannot connect to the mashup data source. See error details for more information.Hide details
Underlying error code: -2147467259 Table: DB bla_bla.
Underlying error message: Data on the server had an unexpected format. It might be possible to fix this by setting the 'OldGuids' option to true.
DM_ErrorDetailNameCode_UnderlyingHResult: -2147467259

The suggested solution is already in place. "It might be possible to fix this by setting the 'OldGuids' option to true."
This is my query string:
= MySQL.Database("localhost:####", "DB", [ReturnSingleDatabase=true, OldGuids=true])
Any idea of the root cause and how to fix this?
Thanks!

Hey,
Wanted to update and summarize the issue.
Issue - In general there are issues with connections to MySQL DBs from Power BI. The symptom in my case was that data refresh did not work and failed with the error message in my first/original post.
Solution - Creat a connection string to MySQL DB with the query in it. For example:
= MySQL.Database("localhost:3306", "DB_Name", [ReturnSingleDatabase=true, OldGuids=true, Query="select * from MyTable where MyCondition"])
There is no need to delete or re-create the original connection string. Just to update it.
Thank you @GilbertQ and @v-frfei-msft for your assistance.
Cheers!

Hi @v-frfei-msft,
I am not sure how this is related. As I can see the imported data.
Anyhow, Can I modify the existing connection? And just enter the SQL statement?
I don't want to re-build the report(s) after creating the new datasource.
Renaming the DS does not matter, the report still points at the original one.
Cheers!
Thanks!
Hi @GilbertQ
Yes, connectivity is good.
Moreover, I have other datasources on the same server and they work fine. For example a MS SQL DB.
Seems like it is related to MySQL DB only and not other data sources.
Cheers!
