Unable to create data source. OAuth login through the on-premises data gateway was unsuccessful

[Sagars_vCon]

Hi,

I'm trying to add a custom connector(.mez file) as a data source to the gateway, so, that the report can be set to schedule refresh.

Right now schedule refresh button is greyed out and even this data source setup is giving an error - 

Unable to create the data source. OAuth login through the on-premises data gateway was unsuccessful. Specific error details are available below and in the gateway logs.

Details: A non-serializable exception was encountered.

Is this something to do with the Authentication mode? Right now it is set to oAuth2 by default and no other options are available in the dropdown. On clicking Edit Credentials, it opens, signs in and then closes the pop-up automatically, and then shows the error that I mentioned above.

Some help will be much appreciated.
Thanks in advance.

Hi @v-kkf-msft,

I was also able to reach till this level, but as soon as I click on edit credential and finish the login then I get this error and due to that data source creation process never gets completed.

I tried doing this on Incognito mode too, and there I could clearly see that once I enter Bentley ID it log me in using SSO but then I get this error while clicking on the create button.

Let me know if it lets you to create the datasource.

Hi @Sagars_vCon ,

I was also unable to successfully create credentials. I think the reason is the connector, maybe you can try asking the developer of this connector.

Hi @v-kkf-msft ,

I'm relatively new to this, but, I tried adding that TestConnection section too and it didn't work. I can share the link of that publicly available custom connector here, would you mind taking a look at that?

Thanks in advance

Hi @Sagars_vCon ,

I am testing with the latest version of the standard gateway. First we need to make sure that the SYNCHRO4D connector is shown in the connector page of the gateway. 

Then enable "Allow user's custom data connectors to refresh through this gateway cluster" in the gateway settings. 

Then I can enter the credentials using the OAuth2 authentication method.

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

Hi @Sagars_vCon ,

For custom connectors to work with the on-premises data gateway, we need to implement a “TestConnection” section in the custom connector’s code. Please make sure your test connection is working.

For more information, please refer to:

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
