Metamask mobile 5.10.0 not suggesting gas fee on custom hardhat node network

[0xHristo]

Describe the bug

I have set up custom hardhat node which I have added to the Metamask mobile app. Every time when I try to submit transaction the Metamask app is not suggesting any gas and I cannot send the transaction, if I try to send it I am getting internal JSON RPC error.

Screenshots

Expected behavior
I expect Metamsk to suggest and fill the gas price fields

Smartphone:

• Device: iPhone12, iPhone13 Pro, Shaomi Mi MI 5 Light, Google Pixel 5, Honor Play
• OS: iOS16, iOS16, Android 15, Android 15, Android 9
• App Version - 5.10.0 (It works on 5.9.1)

I've tried on all of the above phones and it doesn't work on version 5.10.0 but it works on 5.9.1

Hi @tommasini,

May you provide me with further information about the resolving of this issue. How long it will take to resolve it? Should I expect it resolved in 5.10.1? If yes, when is the release of the 5.10.1?

Thank you in advance!

[tommasini]

Thanks for your patience, a fix already have been developed, and it's about to be available in the stores on version 5.11.0

In Android, until it is available you can download the apk of version 5.9.1 here on our GitHub repo https://github.com/MetaMask/metamask-mobile/releases/tag/v5.9.1

Hi @tommasini thank you for the fast response. I have downloaded the updated version and it works fine on the normal transactions but when I try to do approve transaction it still has the above issue. The value is not NaN but instead it is totally missing.

@0xHristo Thanks for update the issue!

We are not being able to reproduce it on ethereum mainnet and on polygon mainnet, using the app.aave.com with an IOS on Version 5.11

Could you help us with more information?
It would be awesome the steps you do and the network rpc URL and chain id that you are using to reproduce this bug

@tommasini hi,

This is the information needed to reproduce the transaction.
I want to note that I am using WalletConnect to connect with Metamask.

rpc URL: https://2488-206-189-108-140.ngrok.io/
chaid id: 31337

the transaction which I am trying to send(basically ERC20 approval to the USDC token smart contract address)

{
  "id": "1669044200605642",
  "jsonrpc": "2.0",
  "method": "eth_sendTransaction",
  "params": [
    {
      "from": "0x0e1751fb76a2f4a8288c0af347def0d5fd5313a7",
      "data": "095ea7b3000000000000000000000000151087e77a918d33df147e748e3bea54c2c08c21ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff",
      "to": "0x2791bca1f2de4661ed88a30c99a7a9449aa84174",
      "gas": "0x2dc6c0"
    }
  ]
}

The MetaMask's visualisation:

I think the problem is from MetaMask because when I am trying submitting the transaction bellow to the same network everything seems okay.

{
  "id": "1669044699708046",
  "jsonrpc": "2.0",
  "method": "eth_sendTransaction",
  "params": [
    {
      "from": "0x0E1751Fb76a2F4a8288C0AF347def0d5fD5313A7",
      "data": "c04a8a10000000000000000000000000151087e77a918d33df147e748e3bea54c2c08c21ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff",
      "to": "0x2791bca1f2de4661ed88a30c99a7a9449aa84174",
      "gas": "0x2dc6c0"
    }
  ]
}

Hey @tommasini, any updates on this issue. Can I help in some way?

[tommasini]

Hey @0xHristo we tried to reproduce this on goerli network with the usdc smart contract

And we were able to estimate the gas and approve the permission to access the token

[0xHristo]

@tommasini I understand. I agree that it is working on public testnets & mainnets but I hit this issue when I try to submit approval on selfhosted testnet. Please, can you try with the following network:

Network RPC URL: https://2679-206-189-108-140.ngrok.io/ (Fork of the Polygon's mainnet, Forked with Hardhat)
Network Chain ID: 31338

I am trying to submit the following transaction:

{
  "id": "1669044200605642",
  "jsonrpc": "2.0",
  "method": "eth_sendTransaction",
  "params": [
    {
      "from": "0x0e1751fb76a2f4a8288c0af347def0d5fd5313a7",
      "data": "095ea7b3000000000000000000000000151087e77a918d33df147e748e3bea54c2c08c21ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff",
      "to": "0x2791bca1f2de4661ed88a30c99a7a9449aa84174",
      "gas": "0x2dc6c0"
    }
  ]
}

Note: If I try submitting on any other public testnet/mainnet everything is populated just fine but not on the above network.
Note 2: Every other transaction (transfer. transferFrom, etc.) works perfectly fine with the above network.
