Repro steps:
1. Create a shadergraph
2. Create a virtual texture
3. Copy and paste a word with an invalid symbol (such as an exclamation point or a space) into the "Layer Reference" space in the virtual texture options in the node settings in the graph inspector

Expected result: if the bug still reproduces, an error should be printed to the console with a stack trace or line number so the user can more easily figure out what's going on
Actual result: there are errors in the graph but the errors are not printed to the console
