Unable to "Save as Specified User"

[rodneyc-yorkuca]

I am trying to "Save as Specified User" and am hitting the below error

[Save as Root] exit code 1: Sorry, user [personal_account] is not allowed to execute '/bin/sh -c echo "file contents:" >&2; cat <&0 > "$filename"' as [sudo_account] on [server]

I tried the following

CTRL-SHIFT-P
Input <sudo_account>
Select folder/file name
Input <personal_account> password

Then it throws me the above error

Any help would be much appreciated
