Computing .ply output for equirectangular images

Hi, I can't seem to compute depthmaps for equirectangular images. The pipleline outlined in the docs says I should be running the "undistort" command after successful reconstruction, then run "compute_depthmaps". Upon running "undistort" on the example 360 dataset, I get the following error:

I understand that an equirectangular panorama will not need to be undistorted, however the undistorted reconstruction output .yaml, images and tracks are needed to proceed with computing depthmaps.

Basically what I want to know is how we can get a .ply format point cloud from the reconstruction using equirectangular images.

Thanks for your time :)
