Leo Wallet returns "An unknown error occured" for register_user on mainnetbeta (adapter + raw provider paths)

[Skunkchain]

Summary

In a browser app, Leo Wallet fails to submit a transaction for:

• program: hyp_privacy_hub_usdc_v2.aleo
• function: register_user
• network/chainId tested: mainnetbeta and mainnet

This fails through both:

1. official @demox-labs/aleo-wallet-adapter-leo (requestExecution + requestTransaction)
2. direct window.leoWallet provider calls (requestExecution + requestTransaction)

All paths return:
An unknown error occured. Please try again or report it

Environment

• Leo Wallet extension: (please fill exact version)
• Browser: (please fill)
• OS: macOS (please fill exact version)
• App stack:
  • @demox-labs/aleo-wallet-adapter-base@0.0.23
  • @demox-labs/aleo-wallet-adapter-leo@0.0.25
• Function: register_user
• Inputs:
  • u32 origin domain (e.g. 8453u32)
  • [u8;32] origin address bytes
• Fee tested:
  • fixed 1_000_000 microcredits
  • adapter/provider variants with feePrivate true/false

Steps to Reproduce

1. Connect Leo wallet with ON_CHAIN_HISTORY / AUTO_DECRYPT and program scope
2. Build AleoTransaction:
   • address = connected leo public key
   • chainId = mainnetbeta (also tried mainnet)
   • transitions = [{ program, functionName: "register_user", inputs }]
   • fee set (1_000_000 tested), feePrivate true/false
3. Call requestExecution(tx).
4. If it fails, call requestTransaction(tx).

Expected

Transaction prompt/sign + tx id returned.

Actual

Both calls fail with:
An unknown error occured. Please try again or report it

Additional Notes

• Balance is sufficient on wallet.
• Same behavior across multiple payload/input variants:
  • object payloads
  • positional argument styles
  • [u8;32] as literal string and as raw JS array
• This appears to be extension-side rejection before broadcast, with no actionable error detail surfaced to app.
