Failed to convert matches file from VSfM to Theia

I use code from https://github.com/caomw/VisualSFMToTheiaConverter to convert matches file from VSfM to Theia, but when I run ./build_reconstruction --flagfile=../../build_reconstruction_flags.txt I got the following output:

It seems that all tracks are filtered due to bad triangulation angles. Is it because i use the wrong version of Theia? My Theia was cloned from github and I get the matches file of VSfM with https://github.com/colmap/colmap/blob/dev/scripts/python/export_to_visualsfm.py. I can use this matches file to run VSfM, but when convert to Theia, I got the above error.
