Unhandled exception for mySQL database

[Garen Torikian]

I'm not really sure how to resolve this:

sql2graphql --database project_development --output-dir=.

Unhandled rejection TypeError: Cannot read property 'originalName' of undefined

The database user is root and there is no password.

Effectively, one of my tables did not have a PRIMARY KEY set. Here's a diff of a hack I did to work around it:

+        var fields = find(reference.model.fields, { isPrimaryKey: true })
+        var resolver;
+
+        if (fields === undefined) {
+            console.warn('could not find primary key on :');
+            console.warn(reference.model);
+            resolver = null;
+        } else {
+            resolver = fields.originalName;
+        }

         return generateField({
             name: reference.field,
             description: reference.description || opts.defaultDescription + ' (reference)',
-            resolve: buildResolver(reference.model, find(reference.model.fields, { isPrimaryKey: true }).originalName),
+            resolve: buildResolver(reference.model, find(reference.model.fields).originalName),
