    do you type these double quotes around your string?
    vivek vishwakarma via telegram
    yes
    Mikhail Boldyrev via telegram
    try to omit them
    Igor Egorov via telegram
    there will be a problem with retrieval of such value. The string that is going to be a value should not contain double quotes :(
    Mikhail Boldyrev via telegram
    the value has to be a valid JSON string, it is wrapped into double quotes in our code. it is not related to database query formation, so it cannot be an SQL injection. it is just JSON syntax. when it is invalid, the transaction fails.
    vivek vishwakarma via telegram
    ok i will try with out those double quotes.

    Mikhail Boldyrev via telegram
    by the way, json strings are enclosed into double quotes, and on your screenshot I se single. it is not a concern for Iroha, but may be for your app. if you need double quotes in your account detail value, please try escaping them like \"this\"
    vivek vishwakarma via telegram
    🙏 Thanks I have inserted json value with out using any double quotes and also inside json no single quote and again thanks for the above details of json structure will try it let you know.

    @mboldyrev Hi, Is there any size limit to store json_data, if yes can we increase the limit?
    Mikhail Boldyrev via telegram
    yes. it is 4 * 1024 * 1024 symbols
    sorabot
    @sorabot
    Mikhail Boldyrev via telegram
    it is hardcoded by now, but we plan to make it configurable in the genesis block
    Leo via telegram
    That's 4MB for each account detail?
    Mikhail Boldyrev via telegram
    seems right

    I ask again this question if somebody knows how to get transaction hash after command call. I tried this code but returns undefined!
    commands.transferAsset({
    privateKeys: [privateKey],
    creatorAccountId: 'alice@iroha',
    quorum: 1,
    commandService,
    timeoutLimit: 5000
    }, {
    srcAccountId: 'alice@iroha',
    destAccountId: 'bob@iroha',
    assetId: 'asset#domain',
    description: 'Test message',
    amount: '1'
    })
    .then(res => console.log(res))
    .catch(err => console.log(err))

    Hi all! Is it possible to use Iroha using Flutter?

    Ruslan Rezin via telegram
    Hi! Not yet for now. But there are SDK for iOS and Java if your interested in integration of mobile applications.
    Spiros M via telegram
    Thank you very much, is there any other cross-platform development environment that i can use for both android and ios?
    Spiros M via telegram
    sorry i meant i can use Iroha

    you can write your own iroha sdk for flutter
    B V via telegram
    or use react native with js library

    My team currently has a react native app, and I'm currious whether its better to use the js sdk, or write my own api for my backend which is python. Any insight you can give on this?
    sudomann (Will) Willy Njundong via telegram
    One particular feature I am indecisive about how to implement is subscribing to block/transaction status streams

    I think it all boils down to how complex is your business logic and security.

    Iroha sdk is just a wrapper around grpc. You could implement one function, that signs raw protobuf and use only protobuffs. Or write a wrapper to limit protobuf usage in your code

    Hi,

    I am using Iroha for a degree project but I am having trouble getting sth to work.

    With the default admin@test account, I can create accounts, however, I am unable to use the same account to append roles via the iroha-cli. This account doesn't have the append_role permission. How can I work around it?

    Add the permissions you need for the admin role in the Genesis block

    Hi, what's the best way to implement transfer acknowledgment. In other short, I need the intended recipient to sign off before the transfer can be completed.
    Leo via telegram
    I looked at the batch example, which uses a 2 way exchange. I need to implement just one way. Any assistance is much appreciated. Thanks
    sorabot
    @sorabot
    Miller Adulu via telegram
    Can the transfer be made then flagged with a default false boolean. Then the other user revives the request to approve to change that boolean to true to make it valid?

    Actually it's not ideal
