I am getting Error: Bad status on response: 400 error while upload cotract using upload function below is my code

 const wasm = await loadContract(contract);  
    console.debug(`Uploading ${contract.name}...`);
    const receipt = await client.upload(
      signer,
      wasm,
      "auto",
      // `Upload ${contract.name}`
    );
    console.log(receipt);

below is error

Note: my wasm file is around 2.4MB.

[webmaster128]

2.4MB is more than what most chains can accept. A typical limit of the Wasm file is 800 KB. You can probably get the contract much smaller by using the rust-optimizer.

[jasmeenPedalsup]

rust-optimizer reduce contract size from 2.4MB to 327.7kb but now I getting another error

below is my RPC URL and chain-Id

 chainId: "theta-testnet-001",
 rpcEndpoint:"https://rpc.sentry-01.theta-testnet.polypore.xyz",

can anyone explain above error and how can I solve above error?

[webmaster128]

The error

unable to resolve type URL /cosmwasm.wasm.v1.MsgStoreCode: tx parse error

sounds like the network has no CosmWasm support. Could you ask the maintainers of the network about it?
