Hi remove the length and try

use the following:
awk 'BEGIN{FS="[| ]"} {print $2}' file

If you have one space in your file:

awk '{print $1$2}' file

Use OFS. Read here for more info. Then try to put it inside this code. Have a shot at it. good luck
Code:
awk 'BEGIN{FS="|"}
{
 sub(/ +/,"",$2)
 print $0
}
' file1
