Getting 400 Error while preview the lookup activity
Hi Anushka96, dineshkumarravi, josef78,
We are not getting any issue while trying to access warehouse. PFBS for reference. Also Parameters cannot be used as connection strings in Fabric pipelines. Please connect to the source directly rather than using parameters.

Community SupportHi dineshkumarravi,
After thoroughly reviewing the details you provided, I reproduced the scenario again, and it worked on my end. I used it as sample data and successfully implemented it.
This might be an intermittent issue. It is currently working for us. Please let us know if you continue to experience the same problem.

Memorable MemberHi dineshkumarravi ,
the problem is still there. I think there are three different problems or changes in behavior in the last week, but one serious.
1. If in query is some small syntax error, like a semicolon at the end for Oracle DB, it returns a nonsensical 400 error.
2. If the preview contains two columns of the same name it again returns a nonsense error 400
3. If the query is a more complex query and the preview takes more than approximately 100 seconds, it returns error 408. This is different than before, either the preview takes longer than before or there is a shorter timeout. And this is a problem because it is not possible to develop a pipeline with more complex queries.
