Unknown Mashup Exception

Why does my data connection fail randomly for no apparent reason.  About every 5-6 days i get an exception error.  I was doing a demo of powerapp and i get "Failed to load [dbo].[tablename]. An error occurred on server. Server Response. Unknown Mashup Exception. inner exception: Column 'ProviderSpecificDataType' does not belong to table."

 

What the heck is this all about.  One day data connection good.. next day this...

Re: Unknown Mashup Exception

Hi dgsonic,

 

I'm living the same problem since yesterday. I have 3 applications that was working yesterday and today can't access any data in the database (without any modifications on apps). I'm my case, I'm using gateway to access a database SQL Server is 2008 (Microsoft SQL Server 2008 R2 (SP2) - 10.50.4000.0 (X64)).

 

Are you using gateway to connect to database? What your database?

 

Looks like a general problem on Power Apps Data Access Service...

 

If I discover a way to solve this problem, I'll share... please do the same if you find a solution.

Re: Unknown Mashup Exception

I am getting the same errror today on an app I created yesterday. It worked fine when I created it and today I get this error. It actually will submit data to my table but that message pops up when the app is started. I am using a Gateway to connect to my SQL Server 2012.

Re: Unknown Mashup Exception

Yep, same scenario.. I'm using the Gateway to communicate to my on premise SQL 2012 R2 database. These problems keep coming and going.  I can't use this as a real world production app because of these ongoing connection problems.  They appear without me touching the app.

Re: Unknown Mashup Exception

Same problem with me.  My PowerApps was working fine, connecting to an on-prem SQL Server.  It has been working fine for a week but now it doesn't.  Help!!!

Re: Unknown Mashup Exception

Has anybody else got a resolution for this problem so far.  I tried creating a NEW app connecting to a completely new table using the gateway to onPremise SQL connection and getting the same "Unknown Mashup Exception". So now I know it's not my existing table. It's the Gateway to SQL Azure having a problem.

Re: Unknown Mashup Exception

Same experience for me.  New apps using on-prem datasource will not work.  Microsoft can you help?  Please fix!?  Production down!

Re: Unknown Mashup Exception

Same experience for me as well! And I agree that production is down... there is no connection with SQL Server... !

Re: Unknown Mashup Exception

I just created a simple PowerApp using a gateway to SQL Server 2014 and I am also getting the error.  If I find a solution, I'll share.

Re: Unknown Mashup Exception

Does Microsoft monitor this forum, or do we need to call them and tell them that they have a Production Platform down?
