Question

Potential solutions: - Is DatabaseModule a valid NestJS module? - If Sequelize

is a provider, is it part of the current DatabaseModule?
- If Sequelize is exported from a separate @Module, is that module imported within DatabaseModule?
@Module({
imports: [ /* the Module containing Sequelize */ ]
})

Error: Nest can't resolve dependencies of the DatabaseModule (?). Please make sure that the argument Sequelize at index [0] is available in the DatabaseModule context.
