Describe the Problem

eth_decrypt used to work but now its throwing this rejected error even after signing the tx

Error: user rejected action (action="unknown", reason="rejected", info={ "error": { "code": -32603, "data": { "originalError": {  } }, "message": "MetaMask DecryptMessage: User denied message decryption." }, "payload": { "id": 9, "jsonrpc": "2.0", "method": "eth_decrypt", "params": [ "cynO2IeYe/weLFuV3/Ec2hhpxFFg5OU=", "<address>" ] } }, code=ACTION_REJECTED, version=6.5.1)

referenced the following PR and verified my implementation coherent with x25519-xsalsa20-poly1305
#4139

i even tried on the docs and its throwing the same error
https://docs.metamask.io/wallet/reference/json-rpc-methods/eth_decrypt/

is eth_decrypt finally deprecated and no longer supported? whats a suggested workaround to decrypt stored cipherTexts from before the deprecation

Code Snippet

async decryptCipher(cipherTextHex?: string) {
    const metamaskAPI = await this.getConnectedAPI();
    const defaultAccount = await this.defaultAccount();

    if (!cipherTextHex || !cipherTextHex.length) {
      return null;
    }

    const cipherText = ethers.utils.toUtf8String(ethers.utils.arrayify(cipherTextHex));
    const [version, nonce, ephemPublicKey, ciphertext] = cipherText.split(".");

    const cipher = {
      version,
      nonce,
      ephemPublicKey,
      ciphertext,
    };

    const decryptedCipherText = (
      (await metamaskAPI.request({
        method: "eth_decrypt",
        params: [JSON.stringify(cipher), defaultAccount],
      })) as string
    )?.trim();

    ...
  }

This is unrelated to Ethers, but the error you are getting back is from MetaMask directly.

The eth_decrypt was deprecated, and I think you are right, they may have finally pulled the plug entirely on it. There may be a work around in the MetaMask settings, but you would need to ask them. You may possibly be able to downgrade to an older version of MetaMask?

Sorry I can't be more help. :(
