[dashboard][error msg] Can we have specific error info in the error title

[jinghua-qa]

When user encounter error in dashboard, can we show the specific error information rather than 'Unexpected error'?

For example for Missing dataset error, can we show the error title to bubble up as 'Missing dataset' rather than 'Unexpected error'? It will be easier for user to see specific error right away.

@stephenLYZ 🙏 "Missing dataset" should do

Was wondering why we would need to do so? Doesn't the See more part already give more context if needed in this case?

I believe that for user experience the code level error reporting should be blocked and these errors should be placed in the console
