Error in metamask tx

[luk-schweizer]

I am using frames to execute a tx to approve an ERC20 token. Frames is identifying correctly the tx, but when sending to metamask is erroring out with the following message: Invalid token value; should be exactly 64 hex digits long (u256)

This is what I am sending back as tx args to frames:

  {
    chainId: "eip155:8453",
    method: "eth_sendTransaction",
    params: {
      abi: [{
            name: "approve",
            inputs: [
              { internalType: "address", name: "spender", type: "address" },
              { internalType: "uint256", name: "amount", type: "uint256" }
            ],
            outputs: [{ internalType: "bool", name: "", type: "bool" }],
            stateMutability: "nonpayable",
            type: "function"
           }],
      to: "0x0578d8A44db98B23BF096A382e016e29a5Ce0ffe",
      data: "0x095ea7b30000000000000000000000008087039152c472fa74f47398628ff002994056ea000000000000000000000000000000000000000000000003bd94cbeac2ba8000",
      value: "0"
    },
  }

decoded data:

{
  "name": "approve",
  "params": [
    {
      "name": "spender",
      "value": "0x8087039152c472fa74f47398628ff002994056ea",
      "type": "address"
    },
    {
      "name": "amount",
      "value": "69001000000000000000",
      "type": "uint256"
    }
  ]
}

And this is the message that frames is giving me in the modal before sending to MM: Approve to transfer up to 69.001 HIGHER.

MM version: 11.14.5
Coinbase wallet and Wallet Connect are working fine and executing the tx as expected.

Any help is appreciated, thanks!
