forgAE: problem after migration from 1.4 to 2.0


I had to struggle a bit with migrating from 1.4 to 2.0 but almost figured out all the problems. The last problem I faced was that I encountered an issue within forgAE when trying to call a contract-function that doesn’t return any value.

The line in my test looks like this:

await deployedContractNonRecipient.payAndSplit({value: aettos});

The function in the contract is defined as follows:

public stateful function payAndSplit() =
      require(Contract.balance > 0, "contract didn't receive any payment")
      let recipientConditions: list((address, int)) = Map.to_list(state.recipientConditions)
      split(recipientConditions, Contract.balance)
      Chain.event(PaymentReceivedAndSplitted(Call.caller, Call.value, Contract.balance))

And the error I get looks like this:

TypeError: returnType.trim is not a function
      at functions.(anonymous function) (node_modules\forgae-lib\forgae-deployer.js:260:76)
      at process._tickCallback (internal/process/next_tick.js:68:7)

@MartinG can you help me out here?

I have another issue that is more related to the aepp-sdk-js in combination with the standalone-compiler as far as I can judge this.

I am trying to pass in a Map as parameter for the following contract-function:

public stateful function updateRecipientConditions(recipients': map(address, int)) =
      require(sumWeights(recipients') == 100, "sum of weights needs to be 100")
      put(state{recipientConditions = recipients'})

The code in the test looks like this:

let recipientConditions = new Map();
recipientConditions.set(recipientOneKeyPair.publicKey, 15); recipientConditions.set(recipientTwoKeyPair.publicKey, 15);
recipientConditions.set(recipientThreeKeyPair.publicKey, 20);
recipientConditions.set(recipientFourKeyPair.publicKey, 20);
recipientConditions.set(recipientFiveKeyPair.publicKey, 25);
recipientConditions.set(recipientSixKeyPair.publicKey, 5);
await deployedContractOwner.updateRecipientConditions(recipientConditions);

The error I get is this:

Error: Http request for http://localhost:3080/encode-calldata failed with status code 403. Status: Forbidden. 
Error data: {"reason":"Type errors\nCannot unify map(address, int)\n         and string\nwhen checking the application at line 109, column 24 of\n  updateRecipientConditions : (map(address, int)) =>
()\nto arguments\n  \"[object Map]\" : string\n"}

here is the respective branch in our repository if somebody of the team wants to investigate:

Hey @marc0olo,

Monday we will release new version of forgae which will probably resolve these issues at least from first glance. I will dig more about your issue and I will comeback to you.

We have found and fixed the first issue and currently investigating and working on the second one. We will provide new version of forgae with the fixes as soon as possible. I will keep you posted.
Sorry for the inconvenience.

you’re welcome to provide a pull-request to my migration-branch with the fixes :wink:

but if you can’t find time to do so I will do it by myself as soon as the issues are fixed.


Hey @marc0olo we are still working on a fix , because it came bigger than we thought. We are trying to fix and release as fast as possible. If you need a workaround, please ping me and I will help.

Nice, sorry for the delay but you will see that there are a lot of changes. If you need some support please open a post and we will try to help ASAP.


I finished the migration but it seems like the transfer of the aettos within a function-call doesn’t work anymore.

It is called like this:

await deployedContractNonRecipient.payAndSplit({value: aettos});

was there any change? because within the test I receive the error contract didn't receive any payment which my contract throws when there is no amount included in the function-call.

you can find the current state here:

didn’t try it, but remebert that it should be {amount: aettos}

will test this. but in 1.4 it definitely used to be „value“ instead of „amount“. at least this was working in the past.

just wondering :sweat_smile:
