Empty validation error and SHACL UI error on publication

[AdMSilvan]

Describe the bug
When attempting to publish a particular cube on INT it results in a SHACL validation error, but does not specify the source of the error. The SHACL UI link which could be used for debugging is dead (ERR_EMPTY_RESPONSE).

Since there is not apparent

To Reproduce
Steps to reproduce the behavior:

1. Attempt to publish the linked cube.
2. click the SHACL UI link

Expected behavior
Information should be displayed about the source of the validation error and the link should open the SHACL UI to be able to determine which part of the shacl shape failed to validate.

I think the problem is that many dimensions lack the scaleType.
The strange thing is that violations are not reported in the UI and the validation report is not shown in the playground.
I could see the report in the playground only after reformatting the shapes graph using the converter.
I suspect there's something fishy going on with the serialization of shapes (which comes from cube.link). I keep investigating but, in the meantime, I hope you can publish the cube adding the missing scateType to the dimensions

Hi Giacomo
Thanks a lot for investigating the issue. I will be sure to look out for that in the future but having the reports would definitely be helpful!

One of my students experienced the same issue. I checked the configuration of her dataset and I found one "column" without a scaleType. After changing this configuration, the publication process worked well.
Good news!
But the bad news is that the error message is impossible to interpret. Please, generate more user-friendly messages.
