Error when adding endpoint

MathiasVDA commented 1 year ago

Hello,

When adding a SPARQL endpoint with the following settings:

Endpoint: https://linked.ec-dataplatform.eu/sparql

All steps go through well and I get a success message at the end stating the properties of the endpoint. But when I click 'Yes' to add the endpoint, then I receive the following error:

An error has occurred while executing Python code: 

TypeError: Object of type set is not JSON serializable

This happens when the "add endpoint permanently" option is selected. When it isn't, the error doesn't occur. Afterwards, the endpoint seems to have been added to the list but when I restart QGIS, the endpoint is no longer in the list. I assume something is wrong when trying to permanently save the endpoint.
