svnlook history is not working with a subpath?

[Laurens Rodriguez]

Hello,
I'm trying to get the history of a subpath from a repository with:
    /usr/bin/svnlook history -r 1000 -l 5 /path/to/my/repo /trunk
I'm sure the path /trunk exists, but it is failing with:

REVISION   PATH
--------   ----
svnlook: E160013: File not found: revision 1090, path '/trunk'

If I try with:
    /usr/bin/svnlook history -r 1000 -l 5 /path/to/my/repo /
or omitting the path completely:
    /usr/bin/svnlook history -r 1000 -l 5 /path/to/my/repo

it works as expected:
REVISION   PATH
--------   ----
    1090   /
    1089   /
    1088   /
    1087   /
    1086   /

I need this info to show the changes from a particular path, not the root
path. I have tried different paths and combinations but I can not figure
how to get this to work. Any help?
My version is:

svnlook, version 1.9.7 (r1800392)
   compiled May 21 2022, 07:24:25 on x86_64-pc-linux-gnu

Thanks!
