Problem

This error usually indicates that the {% parameter parameter name %} liquid variable is being used somewhere where it's not accepted.

Solution

Since the _parameter_value variable is accepted in more places than parameter parameter name (notably the html, link, and sql_always_where parameters) it's usually safe to say you can use this instead.

this

sql_always_where: {% if parameter_name._parameter_value == 1 %} ...

instead of this

sql_always_where: {% if parameter parameter_name == 1 %} ...

Additional resources

Another potential cause of the error is the incorrect use or reference of templated filters in derived tables. See the Templated Filters and Derived Tables Community Post for more troubleshooting tips and information.
