Error when running create-db.bat during 3DCityDB setup

[Crane336]

Hello,

I encountered the following issue while setting up 3DCityDB.
When I execute the create-db.bat script, the process starts normally but eventually stops with the following error message:

Checking spatial reference system for SRID 2326 ...
SET
DO
CREATE SCHEMA
SET

Setting up database schema of 3DCityDB instance ...

psql:D:/Desktop/3dcitydb-5.1.0/3dcitydb-5.1.0/postgresql/sql-scripts/schema/objectclass-instances.sql:6:
ERROR: syntax error at or near ":"
LINE 2: VALUES (1, null, 'Undefined', 1, 0, 1, @core:Undefined@);

I followed the installation guide strictly and did not modify any configuration files.
Could you please help me identify the cause of this error and how to resolve it?

Thank you very much for your assistance.
