SAP Datasphere graphical view deployment issue

[bohdan_kureshov]

Hello experts,

I have a graphical view in SAP Datasphere, which works fine. I have changed it many times and everything was fine. Suddenly I've got the error message: "Model could not be saved. Unexpected token 'c', "csn.query.column" is not valid JSON" or "Model could not be deployed. {"message":"Unexpected token 'c', \"csn.query.column\" is not valid JSON"}" depends on what I want to do save or deploy.

I can't save or deploy the view. I can't restore old version because of the same error (even if it's really old version). I've checked all predcessor views - everything is fine. When copy SQL code from this view to new SQL-view and try to deploy - everything is fine. If I do Save as new view and deploy it - it also works fine.

It's also affected successor views - they have the same errors. The last thing I did before the issue was changing size of measure with type decimal. I don't understand is it one time bug, so I just need to create a new view and replace all occurences of old view with this one, or do I have some issue which can break my model in future again.

This issue was resolved by first re-deploying the dependent views, which were causing design time errors. In cases where the dependent view was failing, we created copies of the views and replaced the main view with them. All objects are now active. Thank you all for your tips!
We hope SAP will find the root cause and send in the fix with the next update.
