I created a result source with opensearch 1.0/1.1 protocol. The credential information is set to Basic authentication with username and password.

When trying to use the result source, I get the following error message

I do check the searchDB for table MSSSources. Verified authInfo is there. What could be the possibility with the error message?

Hi,

According to your post, my understanding is that you got an error when tried to use the result source.

You can set it to anonymous search, then check whether it works.

There is a similar thread for your reference.

Hi Jason,

Thanks for the feedback.

Is there any way to get it working with the credential ? Anonymous working in my scenario, as I don't want any anonymous to be able to use it.

Hi,

I searched for a while, and then found that maybe it could not be worked with credential.

Thanks & Regards,

Jason

Hi all.Has anyone ever solved this issue? We're especially interested in getting this out-of-the-box or with a simple workaround to work with the user's credentials passed through. Any ideas?
