Solutions

1. Build the graph programmatically with the EntityGraph API when using the modern parser mode.
2. Or switch the graph parser mode to legacy if textual parsing is required.

When it happens

Trigger: Thrown while parsing entity graph text that does not conform to the expected format for the configured parser mode.

Common situations: Typical situations: including an entity name where the legacy strategy forbids it (or omitting it where required); using parse() with the modern parser mode selected.
