Upload that image.

try setting a higher timeout value and see if this solves your issue.

you can see from the image that there is no map frame. And no base_link either. What is your current setup? What are you using for publishing odom and map frame?

Like @Choco93 said, there is neither a base_link or a map. Therefore there can't be a transformation between base_link and map. Rename "frame" to "base_link" in your urdf. But you don't have any map, do you plan to run localization (e.g existing map + AMCL) or create your own map using SLAM?

I currently have a map, and to create one my gmapping is running fine.So now i will change frame to base_link now.
