When using Jinja2 expressions it is not valid to use {{ }} around a
variable inside another expression.
You had:
{{ hostvars[{{target}}]['mysqluserpass'] }}
You need
{{ hostvars[target]['mysqluserpass'] }}
Which also, thankfully, is easier to read too.
Can also be written
{{ hostvars[target].mysqluserpass }}
