syntax error at or near ":"

I have this at the top of my api/app.js file

require('pg-spice').patch(require('pg'));

but down in one of my controllers I get the error stated above 

and from the database

``` sql
 ERROR:  syntax error at or near ":" at character 42
STATEMENT:  SELECT * FROM v2_sp_get_queue_operations(:application_token::uuid, :limit::integer);
```
