user4129: I cant seem to figure out whats going on? Ive been trying to create a transaction which sends ADA to a specified wallet address and can't seem to get it to work.
type Schema =
        Endpoint "storeFront" PaymentPubKeyHash

payPubHash :: PaymentPubKeyHash
payPubHash = "3f7846896a48c59359746ff096d63606ceb82e65900d20a9fd2b8a93"

storeFront :: AsContractError e => Promise () Schema e ()
storeFront = endpoint @"storeFront" $ \(payPubHash) -> do
    unspentOutputs <-  utxosAt contractAddress
    
    let 
        tx       = Constraints.mustPayToPubKey payPubHash (singleton adaSymbol adaToken 30000000) 
    void $ submitTxConstraintsSpending storeContract unspentOutputs tx
        
contract :: AsContractError e => Contract () Schema e ()
contract = storeFront

endpoints :: AsContractError e => Contract () Schema e ()
endpoints = contract

mkSchemaDefinitions ''Schema

$(mkKnownCurrencies [])

here's the error
Compilation Error, Line 93, Column 12 (jump)

user255: It appears you are trying to assign a type of Promise to a type of Contract
contract :: AsContractError e => Contract () Schema e ()
contract = storeFront

Why not try this, instead:
contract :: AsContractError e => Contract () Schema e ()
contract = awaitPromise storeFront
