Metamodel creation error.

Question

Metamodel creation error.

1 view

Hi, I created multischema data source using PostgreSQL. In Business Model Catalog I want to create Metamodel. And after clicking on the “META WEB”, I get errorbox: "Errors while attempting to load the datasource Error while getting structure of data source by id". Which of the solutions? With regards.

Error log:
