Yes, if you undo this commit: https://redmine.postgresql.org/projects/pgadmin4/repository/revisions/97e39699ead1005a4a5ef8e986d980df8f743db9
This was a fix of a bug that occurred when querying a table with no columns. It displayed the same error mentioned in the original email and was due to a JS error. You can either checkout a previous commit or simply undo the difference in sqleditor.js manually, it is only 2 lines of code. Then try querying a table with no columns. Your explanation seems legit to me but I am no expert in JS.
