Timeout in query with many parentheses

[DominicWuest]

When running the following query:

RETURN (((((((((((((((((((((((0)))))))))))))))))))))))

I encountered the following error:

read tcp [::1]:<PORT>->[::1]:6379: i/o timeout

I believe the query mentioned above is semantically and syntactically correct and thus no error should be thrown here.

It seems like this points to a potential performance issue, as when removing parentheses, the query execution time accelerates.
Additionally, on other systems, the query wasn't enough to induce the error message, but after adding more parentheses, it appeared.

I encountered this issue when testing queries on the FalkorDB master branch in a Docker container running redis:7.2.3-bookworm.

Steps to reproduce

Run the following query and observe it throws an error:

RETURN (((((((((((((((((((((((0)))))))))))))))))))))))

Expected behavior

The query should run successfully

Actual behavior

The query fails with the error message read tcp [::1]:<PORT>->[::1]:6379: i/o timeout
