使用Golang SDK部署AEX9 fungible-token合约报错求助

Hey there, since I can’t see the exact error message and method parameters from your images, let me walk you through the most common issues and fixes when deploying an AEX9 token using the Go SDK—these usually cover 90% of the cases folks run into.

• Check SDK Version Compatibility
  Make sure you’re using the latest stable version of the Algorand Go SDK (or the version specified in the AEX9 implementation docs). Outdated SDKs often have breaking changes with newer network APIs. Run go get -u github.com/algorand/go-algorand-sdk/v2 to update, and double-check that your code aligns with the SDK’s current method signatures.

• Validate AEX9 Metadata & Parameters
  AEX9 tokens require specific metadata fields that are easy to misformat:

  • Ensure totalSupply is a valid uint64 value (no negative numbers, no decimal points—decimals are handled separately via the decimals field).
  • Verify that decimals is between 0 and 18 (inclusive), as this is the standard range for fungible tokens.
  • Make sure your metadata JSON is properly structured and doesn’t have typos (e.g., Symbol instead of symbol—case matters in most implementations).

• Verify Network & Account Setup

  • Confirm you’re connected to the correct network (testnet/mainnet) and that your node’s API endpoint is reachable. Test with a simple status call using the SDK to rule out connectivity issues.
  • Check that your deployer account has enough ALGO to cover the transaction fees and the minimum balance required for creating an asset. For testnet, you can fund your account via the Algorand dispenser.
  • Ensure the account’s private key/mnemonic is correctly loaded into the SDK—invalid credentials will throw authorization errors every time.

• Debug Transaction Construction
  Before sending the deployment transaction, print out the full transaction object (using fmt.Printf("%+v", txn) or similar) to inspect:

  • The AssetConfigTxn fields (especially AssetTotal, AssetDecimals, AssetName, UnitName) match your intended values.
  • The Sender address is correct, and the Fee is set to a reasonable amount (not too low, which can cause the transaction to get stuck).

• Check for AEX9-Specific Implementation Issues
  If you’re using a pre-built AEX9 template, make sure you haven’t modified any critical parts of the contract logic:

  • Some templates require that the mint function is only callable by the deployer (if you’re trying to mint during deployment, ensure the permissions are set correctly).
  • Verify that the asset’s freeze/clawback permissions are configured as intended—disabling them when you meant to enable (or vice versa) can lead to unexpected errors.

If after going through these steps you’re still stuck, could you share the exact error message (copy-pasted text is better than images!) and the relevant code snippets for the method you’re calling? That’ll help narrow down the issue quickly.
