pgadmin4/EnterpriseDB 9.0.4

Hello list,

I have problems using pgAdmin 4 in combination with EnterpriseDB 9.0.4. Connection works, but when clicking on any sub-items ("Schemas", "Catalogs") no details appear.

logfile excerpt:

Is pgAdmin designed to support EnterpriseDB 9.0.4?

Thanks for any help,
