utxosAtAddress returning empty list

[Fiftyw3bs]

I'm confused as to why the following occurs.

To prove ownership of a token, the validator expects that a certain token is referenced, which is implemented so:

membershipProof <- mapM (\pAddr -> provePossessionOfMemberToken' pAddr
                                                                  colonySettings
                                                                  colonyParams
                                                                  (badge ColonyOwner)
                          ) $ cpCreators colonyParams

Unit test works fine but when deployed, I get the unusual issue where utxosAtAddress returns an empty list, when the length of cpCreators colonyParams is greater than 1.

The log for when the length is 1:

[sourabhxyz]

And does those addresses actually have UTxOs if say checked via a block explorer?

[Fiftyw3bs]

Yes, they do. Both requests (length =1 and length =2) were run within just 2 minutes interval - according to the log. And also within the same process

[sourabhxyz]

In your log, could you try printing out fetched UTxOs? Or is getAssetClassTxOutRef already doing it without any filtering? And what blockchain provider are you using?

[Fiftyw3bs]

Yes, getAssetClassTxOutRef already displays the utxos without any filtering.

I've tried it with both Blockfrost and Maestro to no avail.

[sourabhxyz]

Can you try printing UTxOs at an address outside your current program using Atlas? If it correctly gives out UTxOs then likely it's an issue with your code.

[Fiftyw3bs]

The UTxOs are being fetched successfully even within my program. Even my unit test, that tests the multisig, works pretty fine without any issues. It is only when deployed that I face this issue.

This is the log from the unit test:

[sourabhxyz]

It is only when deployed that I face this issue.

That's very weird and imaginably difficult for us to debug unless you provide a minimal reproducible example.

[Fiftyw3bs]

Understandable... Here is the implementation of the function:

provePossessionOfMemberToken' :: (HasCallStack, GYTxUserQueryMonad m)
                              => GYAddress 
                              -> ColonySettingsParams
                              -> ColonyParams
                              -> ColonyBadgeParams
                              -> m (Maybe (GYTxSkeleton 'PlutusV2))
provePossessionOfMemberToken' memberAddr 
                              colonySettings 
                              colonyParams 
                              colonyBadgeParams 
                              = do
  let mintingPolicyId'        = mintingPolicyId $ colonyMintingPolicy' colonySettings colonyParams
      mType                   = cbpRole colonyBadgeParams
  tName                       <- tokenNameFromPlutus' $ fromColonyTokenTypeToTokenName mType
  memberTokenRef              <- getAssetClassTxOutRef memberAddr (GYToken mintingPolicyId' tName)
  gyLogDebug' "" $ printf "[provePossessionOfMemberToken'] memberTokenRef ::::::::::::::::::::::::: %s" (show memberTokenRef)
  case memberTokenRef of
    [] ->  return Nothing
    memberTokenRef':_ -> do
      let skeleton                = Just $ mustHaveRefInput memberTokenRef'
      return skeleton

getAssetClassTxOutRef :: GYTxUserQueryMonad m
                      => GYAddress
                      -> GYAssetClass
                      -> m [GYTxOutRef]
getAssetClassTxOutRef addr asc = do
  utxos <- utxosAtAddress addr $ Just asc
  gyLogDebug' "" $ printf "[getAssetClassTxOutRef] utxos: %s" (show utxos)
  return $ utxoRef <$> utxosToList utxos

And here's how it's being called:

membershipProof <- mapM (\pAddr -> provePossessionOfMemberToken' pAddr
                                                                  colonySettings
                                                                  colonyParams
                                                                  (badge ColonyOwner)
                          ) $ cpCreators colonyParams
