SqlFluff RuntimeError Triggers Server Error 500 in Frontend

[reata]

Describe the bug

• A clear and concise description of what the bug is.

SQL
Use trino dialect:

INSERT INTO xxx SELECT * FROM yyy;

As of sqlfluff 2.3.2, sqlfluff trino dialect doesn't support this yet. So it causes the following exception:

RuntimeError: Grammar refers to the 'Overwrite' keyword which was not found in the trino dialect.

The syntax in the query is not (yet?) supported. Try to narrow down your query to a minimal, reproducible case and raise an issue on GitHub.

Or, even better, see this guide on how to help contribute keyword and/or dialect updates:
https://github.com/sqlfluff/sqlfluff/wiki/Contributing-Dialect-Changes#keywords

To Reproduce

The web server returns 500 to frontend, and due to this is not in JSON format, frontend fails to parse it. It only shows:

Unexpected token 'A', "A server e"... is not valid JSON

Please check your SQL code for potential syntax error in Script View.

Expected behavior
Frontend to show the exact same error message as in backend.
