unable to resolve type URL /cosmwasm.wasm.v1.SetGaslessContractsProposal

[quanpt239]

I tried to add a proposal for gasless contract with the following content

{
  "messages": [
    {
      "@type": "/cosmwasm.wasm.v1.SetGaslessContractsProposal",
      "authority": "orai10d07y265gmmuvt4z0w9aw880jnsr700jf39xhq",
      "contracts": [
        "orai1nc5tatafv6eyq7llkr2gv50ff9e22mnf70qgjlv737ktmt4eswrq3e4sxg"
      ]
    }
  ],
  "metadata": "foobar",
  "title": "gasless",
  "deposit": "10000000orai",
  "summary": "gasless",
  "expedited": false
}

But I got an error below

How can I add a proposal gasless contract on cosmos v0.50 properly?

I found out that this problem is similar to #4. I just need to implement message set contract gasless and its handler to add proposal.
