@jngz-es Did you install the arrow-flight-rpc plugin? The _flight/info REST handler is implemented in that plugin.

Hi @andrross and @rishabhmaurya , I installed arrow-flight-rpc and figured out where the bug is. I am publishing a fix pr soon.

Closing this issue. @jngz-es please re-open if there is still an issue.

Hi @andrross , sorry for the confusing words I said. What I meant was that the issue is there with the arrow-flight-rpc plugin installed. Then I debugged the issue, and found the root cause. I just published the pr to fix it.
