Create msgGrant have error "tx parse error"

[tungleanh0902]

I'm following this doc (https://www.npmjs.com/package/@cosmology/telescope#grpc-gateway-client) to create a multisig msg for typeUrl: "/cosmos.authz.v1beta1.MsgGrant" and we have typeUrl: "/cosmwasm.wasm.v1.ContractExecutionAuthorization", in it. But when I boadcast my transaction, it emits this error: "tx parse error". I'm using your latest version. Where am I wrong here? Can you give me a example for this? Here is the code:

window.keplr.defaultOptions = {
                sign: {
                    preferNoSetMemo: true,
                    preferNoSetFee: true,
                    disableBalanceCheck: true,
                },
            };
            const offlineSigner = window.getOfflineSignerOnlyAmino(
                chain.chain_id
            );
            const signAccount = await getSequence(chain.api, multisigID)
            const { grant } = cosmos.authz.v1beta1.MessageComposer.withTypeUrl;
            const msg = grant({
                granter: 'migaloo17gayusvse9e9espd0ym66eju5jymshsz6etlx0',
                grantee: 'migaloo1g77s6rh7fgdfcwgcxpwwzr5ujamf302krvua0v',
                grant: {
                    authorization: cosmwasm.wasm.v1.ContractExecutionAuthorization.toAminoMsg({
                        grants: [
                            {
                                contract: 'migaloo14hj2tavq8fpesdwxxcu44rty3hh90vhujrvcmstl4zr3txmfvw9s58v48z',
                                limit: cosmwasm.wasm.v1.CombinedLimit.toAminoMsg({
                                    callsRemaining: BigInt("100"),

                                        }
                                    ]
                                }),
                                filter: cosmwasm.wasm.v1.AcceptedMessageKeysFilter.toAminoMsg({

                        ]
                    }),
                    expiration: new Date(Date.now() + 60 * 60 * 24 * 7)
                }
            })
            console.log(msg);
            // const signingClient = await getCustomClient(types, offlineSigner);
            const signingClient = await getSigningCosmosClient({

            const broadcaster = await StargateClient.connect(chain.rpc);
            const result = await broadcaster.broadcastTx(
                Uint8Array.from(TxRaw.encode(signedTx).finish())

Hi, Thank you for the feedback!

We tested Grant and Revoke functions and passed in this test: https://github.com/cosmology-tech/telescope/blob/main/packages/starship/__tests__/v1/authz.test.ts

The test's using some features that we recently upgraded and we'll update docs very soon: https://github.com/cosmology-tech/telescope/blob/a6f00deb22d3a41a7b8c832b750ec078328014f6/packages/starship/scripts/codegen.js#L104

Hope these make sense, any problem please let me know.

Thank you very much!

Hi. Thanks for your reply. I can create msgGrant with single signature using proto signing but not multisignature case. And I think that the sdk require direct signing for single signature transaction but amino signing for multi signature transaction. I tried both direct and amino and it fails. So can you have a test for multi signature case?

Ok, we'll give it a try in these days!

So do you have any news? I think the problem here is how the sub typeurl is encoded in amino-json sign mode and the sdk don't understand it. I try many ways to encode it but nothing work.

Thx! recently we've had some clues for this, will try to fix asap!
