There wasn't actually an *error*. E4defrag doesn't need root prives to find and print statistics. It doesn't deliberately because the people who wrote the program decided this was the right thing to do. So it's not actually hiding the error, it's just doing something weird/stupid. Which you could argue is a bug, but if so, it's more of a design issue. (It's not like it's secret; and you get the same information using filefrag.)

OPTIONS -c Get a current fragmentation count and an ideal fragmentation count, and calculate fragmentation score based on them. By see‐ ing this score, we can determine whether we should execute e4defrag to target. When used with -v option, the current frag‐ mentation count and the ideal fragmentation count are printed for each file. Also this option outputs the average data size in one extent. If you see it, you'll find the file has ideal extents or not. Note that the maximum extent size is 131072KB in ext4 filesystem (if block size is 4KB). If this option is specified, target is never defragmented. I am attaching a screenshot of my output which is not what I expected. This may not be a bug but it is not very informational.
