GraphQL error when EDG populates a valuetableviewer

[Tim Smith]

Hi,

Let me know if this is best asked via a support ticket...  

I am suddenly receiving GraphQL errors when an instance is rendered using a value table viewer.

Is there a known cause for the error shown below?  The data graph that holds these instances is populated by importing a TTL file that is generated outside of EDG.  The only change I made was to create a new data graph and import a new ttl file (which is 98% the same as the previous one).  I could understand an error if the triples had changed but checking the source code for the instances, they are the same between the old data graph and the new one.  The old file renders properly using the same shape definitions.

I'm at a loss as to where to look to identify the error.  It feels like it is something at the graph level but I'm guessing.

This happens using EDG 7.1.3 and 7.2.1

Thanks in advance for your help,

Tim

Hi Tim,

from the syntax the {} blocks indicate that no column properties have been found. The columns of the value table viewer are determined from the sh:class or sh:node of the (parent) property. Are you sure these can be found and do have properties?

If this doesn't help, a good next step for me would be to see the definitions, e.g. in a private email if you prefer.

Holger

Thanks Holger!

Your response gave me a clue where to look.  I erroneously changed an import (include) such that the Node Shapes that define the table structure of the Value Table Viewer were no longer accessible to the instance graph.  In the case below, the Composed of Table View node shape was not accessible even though the property shape shown was.

The "{}" in the error message was nagging me that something was missing but I didn't know what was supposed to be there.  I need to learn more of GraphQL's syntax so I can better understand what the error messages are telling me.

Thanks again for your help,

Tim
