encodeUint64(asset_id) doesn't work

General

I’m trying to push the assetID to app.Args by encoding it to uint64 but its giving error

console.log(algosdk.encodeUint64(12345))

It was working fine recently but now it giving issues.

i am using algosdk 1.24.1 without any issue…

appArgs.push(algosdk.encodeUint64(123)); works for me well…

you probably installed some dependency which downgraded/changed buffer library?

I did use this version just 2 minutes ago and still got same error

4

Which version of node JS and algosdk are you using?
Are you using browserify or similar?
You may need to upgrade some of those.

5

node 14.17.0 and algosdk 1.24.1

6

i am using node v16.18.1 …

7

It looks like node v14.10 or after should work as this function was added in v14.10:
https://nodejs.org/api/buffer.html#bufwritebiguint64bevalue-offset

So my guess is that you’re using a framework/toolchain that is somewhat not providing this function.
It looks you are using react, but which toolchain are you using:
create react app, next.js, gatsby, vite
?
Which version?

Maybe posting package.json may help.

@fabrice I am also facing same issue with algosdk 1.24.1 and node version 18.12.1, getting error on algosdk.encodeUint64() method

i suggest to put this into your test cases

  it("encodeUint64", function () {
    expect(Buffer.from(algosdk.encodeUint64(123)).toString("hex")).toBe("000000000000007b");
    expect(Buffer.from(algosdk.encodeUint64(123123123123123)).toString("hex")).toBe("00006ffad60473b3");
  });

if it fails, there is issue with algosdk or some dependencies… if it goes through the issue is somewhere else

Can you show the exact error?
Are you using a framework such as create-react-app, next.js, gatsby, vite…?
Can you try to add the test suggested by @scholtz above?
Can you post your package.json (e.g., in Github gist)?
Can you create a fresh project with only algosdk and an index.js file that just test encodeUint64 and nothing else?
