Postgresql – Cannot read property 'map' of undefined when creating a graph in AGE Viewer

I have PostgreSQL 15 running with the Apache AGE extension installed on it. I can view graphs and run queries using AGE Viewer, but I get the following error when creating a new graph from AGE Viewer.

Screenshot of the error

I restarted AGE Viewer, but still, it didn’t work. I expected a new, empty graph to be created if it worked properly. Does anyone know how to fix this?

    The error is occurring because the object on which you are using map function is undefined.

    • Make sure that the object on which you are using the map function is properly initialized.
    • Object should contain valid data for using map on it.

    I believe you cannot create an empty graph using this functionality; you have to upload a CSV file.id

    There’s an issue open for this.

    However, using a simple query like the one below can generate an empty graph for you:

    SELECT ag_catalog.create_graph('graph_name');

    OR

    SELECT create_graph('graph_name');
