Status Code 500

I am encountering a status code 500 message when I try to modify an existing dataflow. This happens for several dataflows. I can no longer save changes made to a dataflow. This is happening in dev, test, and prod. I first noticed it today. I was able to make changes to dataflows just a few days ago. These dataflows use Azure data, OneDrive Excel data, and Sharepoin Excel data. I need a solution soon. I have included the message below.

No solution has been provided, but the issue went away on its own. Not really a solution. Maybe the man behind the curtain is resolving it without letting anyone know.

disable the parameter query from loading. 

That's what worked for me

Hm, it's 2023 and I am getting the same error message?!?!


Why can't we get error messages which let us know what is actually wrong?

I am having the same error with several dataflows. They all refresh normally, but as soon as I try to make a change and save, it pops up the internal error.

This is still happening.My scenario is when I edit a query that has been set for incrimental refresh.  I edit it to pass the range params to a function that folds them into the sql for an odbc query.


    //Source = ODBC_BLP800CFBL(SalesOrdersSQL,pFrom, pTo)
    Source = ODBC_BLP800CFBL(SalesOrdersSQL,RangeStart, RangeEnd),
    #"Changed column type" = Table.TransformColumnTypes(Source, {{"DATE", type datetime}}),
    #"SalesOrders-44415445-autogenerated_for_incremental_refresh" = Table.SelectRows(#"Changed column type", each DateTime.From([DATE]) >= RangeStart and DateTime.From([DATE]) < RangeEnd)

I am also facing this same error since yesterday. It will be helpful if there is a solution other then setting up the dataflow in a new Workspace. I have got a number of queries and datasets and reports connected to the dataflow so it is not as simple as just recreating everything to a new Workspace.


Here is the error details:

I am getting this same issue, I am unable to save dataflows. (even if i make the tiniest change). this is a good 4 months later, judging from the reply the engineers would have fixed this, is there anything else that can cause this error?

Can i somehow report this issue to MS?



Support page had this appended to the message yesterday: "Engineers have identified the root cause and a fix is expected to be deployed by end-of-day 07/19/2021."

The message is now removed altogether so it should be resolved.

Check the support page--this is a known issue.

EDIT: Message from the support page: "Power BI customers editing existing dataflows may experience errors with the following message: “Cannot perform this operation due to an internal error.” As a workaround customers can migrate their dataflows to a new workspace. Engineers have identified root cause, and an estimated time to mitigate will be provided shortly."
