Message extension based on API throwing "Unable to reach app. Please try again."

Hello SatBhat - Please find below comments on your queries:
1) Regarding NA/NA => We are getting this because of the configuration done in the "previewCardTemplate" like below and we are not getting top level values in the result of API call:

Even if we are getting NA/NA in search result, if you select and post it in the Teams, you will be able to see the actual results.

You may need to update the logic and map the data if we will be able to get those values:

2) Please use same 3.0.1 version rather than 3.1.0. Also, I am also using same version and getting proper results:

3) Your zip package should contain all of below files:
