Bash: Couldn't resolve the unexpected token syntax error

Aim: I'm trying to set up VVV where I'm intending not to run DB backups by default, on specific databases.

Where I'm stuck: I keep getting the syntax error near unexpected token `done' even when I use line breaks in bash script.

Steps taken: I also ensured that I've the LF line endings in both bash scripts, yet I get the same error.

File: vagrant_halt_custom

#!/bin/bash
#
# This script is run whenever `vagrant halt` is used to power off
# the virtual machine. To customize this behavior, include a file
# in your local VVV/config/homebin directory: vagrant_halt_custom
#
# Look for a custom trigger file. If this exists, we'll assume that
# all trigger actions should be handled by this custom script. If
# it does not exist, then we'll handle some basic tasks.
db_backup_custom

File: db_backup_custom

#!/bin/bash
#
# Create individual SQL files for each database. These files
# are imported automatically during an initial provision if
# the databases exist per the import-sql.sh process.
mysql -e 'show databases' | \
grep -v -F "information_schema" | \
grep -v -F "performance_schema" | \
grep -v -F "mysql" | \
grep -v -F "test" | \
grep -v -F "Database" | \
while read dbname; do if [ "$dbname" == "mydb" ]; then echo "Database $dbname skipped." && continue fi; mysqldump -uroot "$dbname" > /srv/database/backups/"$dbnme".sql && echo "Database $dbname backed up..."; done

Error

==> default: Running triggers before halt...
/home/vagrant/bin/db_backup_custom: line 12: syntax error near unexpected token `done'
/home/vagrant/bin/db_backup_custom: line 12: `while read dbname; do if [ "$dbname" == "mydb" ]; then echo "Database $dbname skipped." && continue fi; mysqldump -uroot "$dbname" > /srv/database/backups/"$dbnme".sql && echo "Database $dbname backed up..."; done'

I figured the following answer after numerous trial and error.

File: db_backup_custom

#!/bin/bash
#
# Create individual SQL files for each database. These files
# are imported automatically during an initial provision if
# the databases exist per the import-sql.sh process.
mysql -e 'show databases' | \
grep -v -F "information_schema" | \
grep -v -F "performance_schema" | \
grep -v -F "mysql" | \
grep -v -F "test" | \
grep -v -F "Database" | \
while read dbname; do
    if [ "$dbname" == "mydb" ] ; then
        echo "Database $dbname skipped." \
            && continue;
    fi
    mysqldump -uroot "$dbname" > /srv/database/backups/"$dbnme".sql &&
        echo "Database $dbname backed up..."; done;

Tip: Use the following command to verify if your bash script has any syntax errors.

bash -n bin/db_backup_custom

There's a missing semicolon after continue.

Any reason you don't format the code to more lines?

while read dbname; do
    if [ "$dbname" == "mydb" ] ; then
        echo "Database $dbname skipped."
            && continue
    fi
    mysqldump -uroot "$dbname" > /srv/database/backups/"$dbnme".sql &&
        echo "Database $dbname backed up..."
done

BTW, the backslashes after | aren't needed as the command can't end with a lone pipe.
