No instance for (MonadResource IO)
arising from a use of `get'
Possible fix: add an instance declaration for (MonadResource IO)
In a stmt of a 'do' block: Just dc <- get declId
In the expression:
do { Just dc <- get declId;
getDbModule dc }
In an equation for `getDbModule':
getDbModule (DbConstructor _ _ declId)
= do { Just dc <- get declId;
getDbModule dc }
