Some reports doesn't contain credential

[dawcza3]

I'm add reports to existing reports workspace, which contains the same connection string which i got in my raport that i upload.  After trying to embadded it on website, i got message : DMTS_DatasourceHasNoCredentialError. I'm trying to update again my connection string for few methods, but it doesn't help me, i always got the same error on reports that i add to my workspace. Older reports works. 

So, I don't uderstand, how it is possible ? I need to create new workspace whenever I want add some new reports ?

The update connection string works for me, can you double check that you've input the correct datasetid?

In all reports I have the same connection string, to the same database hosted in azure. If I created new workspace and for each report I  update my connection string it works ok ( I mean add report update connection string and add another report and update connection string and again and again...). If I want to upload another report few hours later, it doesn't load on my website ( i got message that it doesn't contain credential which I actually add again after add report). 

So it's very anoying problem because whenever I want add some new reports I need created a new workspace and add all me reports again.

How you upload the report and update the connection string? Via this sample, any change did you make to the code?
