Short description

error:
Mirror Inaccessible', `Could not locate N5 root for mirror 2

More information

Image base given in the stack mirror
http://localhost:3000
which was locally served from
/md0/catmaid/input/1683_raw_merged_red.n5
python3 -m http.server 3000

Folder structure of my n5 file is as follows
/md0/catmaid/input/1683_raw_merged_red.n5/1683_raw/0/1/5
/md0/catmaid/input/1683_raw_merged_red.n5/1683_raw/1/1/5
...
Looks like it is expecting a file format with %SCALE_DATASET%
can u please let me know the exact format of the n5 file expected?

If you're using raw N5, you'll be using tile source 11. What does your stack mirror configuration look like? CATMAID expects a scale pyramid in N5 volumes (but if you only use one level, that's fine). For scale 0, %SCALE_DATASET% is replaced by s0; for scale 1 it's replaced by s1 etc.. So your stack mirror configuration needs a URL which directs points to the root of the array (with attributes.json containing the dimensions, data type etc.), where one of the group names is replaced by %SCALE_DATASET%.
