Inconsistent behavior when connecting to a Odata2 source.

Hi. We are facing an issue when trying to connect to a SharePoint source in Denodo to create Base Views. On Developmet environments we are able to create the views and to use them retrieving data, on the Testing environment they do not. The configuration and the source are the same for both environments. This is the error message we receive. "There was an error while creating this base view: Error while executing custom wrapper method 'getSchemaParameters': com.denodo.vdb.engine.customwrapper.CustomWrapperException" We are using Custom Data Source with Denodo-Odata2-Wrapper.

Hi, The above-mentioned error is due to the incorrect configuration of the data source. In this scenario, I would perform the following checks: * Ensure that the **Service Endpoint** URL provided in the data source configuration of the testing environment is configured correctly as that of the development environment. * Make sure that the steps mentioned in the [Microsoft SharePoint as data source](https://community.denodo.com/kb/en/view/document/Microsoft%20SharePoint%20as%20data%20source) Knowledge Base article are followed correctly. * Also, I would check the **vdp.log** file available in the “<DENODO_HOME>/logs/vdp” directory to identify the root cause of the error. For more details, refer to the [Denodo OData2 Custom Wrapper - User Manual](https://community.denodo.com/docs/html/document/denodoconnects/8.0/en/Denodo%20OData2%20Custom%20Wrapper%20-%20User%20Manual) document. Additionally, if you still need help and are a valid Support user, you may open a Support Case at the Denodo Support Site and the Support Team will assist you. Hope this helps!

Hi. Now the Data source that was working on friday is no longer working. We receive this message: "[CUSTOM WRAPPER] [ERROR] Received exception with message 'Error while getting token refresh. Error message: No OAuth2 refresh token'". We followed the instructions from the manuals, but there are steps missing (how to use the wizard, how to create the authorization server URL, how to check if the URLs provided are valid, etc).
