fi is a reserved keyword

[MohammadBnei]

I have a basic release script with sed and grep, but i cannot convert it to a go module because of the following error :

# generate gives the same error
bunster build release.sh -o release
Error:  syntax error: `fi` is a reserved keyword, cannot be used a command name. (line: 58, column: 5)

Here is the script :

#!/bin/bash
# Trap SIGINT for the whole script and define an exit handler
trap "gum style --foreground 196 'Process interrupted. Exiting...'; exit 130" SIGINT
