I am unable to solve camera motion because of no camera being found on any of the frames

I was trying to use motion tracking but got this warning: Warning: Some data failed to reconstruct (see console for details). I checked the console and it seems that most of the errors are related to no camera being found on all of the frames. Here is the full output:

Does anyone know what the problem might be? All of the trackers go from start to finish and blender doesn’t have any problem tracking them. I wanted to upload the project file here but I am a new user and I can’t upload files yet. Here is a Google Drive link - https://drive.google.com/file/d/1ynS_k_AWXWTtXt9rOQfOPqBRcZCQCGdz/view?usp=sharing.

Did you add a camera to your scene in the 3D window?

You need more trackers. In your dopesheet, red means that isn’t enough trackers to a proper solve, green 8-16 trackers, and gray is when you have more than 17. I suggest that you always have more than 16, manually tracked and evenlly spaced in your whole shot. Think about depth, points close to camera, mid and far, not too far. Concentrate more of them where the CG is going to be.

I added more trackers and it worked. I didn’t know blender had such limits. Thanks!
