seems similar to the bug https://github.com/NodeBB/NodeBB/issues/3489 so you may just need to update your dependencies (rm -rf node_modules && npm cache clean && npm i).
That worked, thanks!
When I am uploading avatar, I got message " spawn convert ENOPEN";
when I check it with "./nodebb log" the error message is shown:
BTW, the nodebb version is 0.70 and installed on a Mac , the "/public/uploads" path permission is ok for write
And it seems it means the file size is too huge, that NodeBB (probably) can't read and gives this error.
the size is less 10K
