# Description
"can't follow stream paths" errors have always been a bit scary and
obnoxious because they give no information about what happens...
in this PR i try to slightly improve the error message by telling if the
stream was empty or not and give span information when available.
# User-Facing Changes
```nushell
> update value (get value)
Error: nu:🐚:incompatible_path_access
× Data cannot be accessed with a cell path
╭─[entry #1:1:1]
1 │ update value (get value)
· ─┬─
· ╰── empty pipeline doesn't support cell paths
╰────
```
```nushell
> ^echo "foo" | get 0
Error: nu:🐚:incompatible_path_access
× Data cannot be accessed with a cell path
╭─[entry #2:1:1]
1 │ ^echo "foo" | get 0
· ──┬─
· ╰── external stream doesn't support cell paths
╰────
```
