I believe the error is because chromium is a shell script wrapper and
not an ELF binary.

I used the following script for those:

--8<---------------cut here---------------start------------->8---
$ cat ~/.local/bin/run-gdb
#!/usr/bin/env bash

(
        wrapper=$(cat $(which $1))
        shift
        . <(echo "$wrapper" | grep ^export)
        binary=$(echo "$wrapper" | grep ^exec | grep -o -E '/gnu/store[^"]*')
        gdb --args "$binary" "$@"
)
--8<---------------cut here---------------end--------------->8---

Then you can do:

--8<---------------cut here---------------start------------->8---
run-gdb chromium
--8<---------------cut here---------------end--------------->8---

Hope that helps,
