Getting the error message of "Invalid ipfsCid" when trying to decrypt the encrypted file uploaded to IPFS using the SDK about js-sdk

[Eric1015]

I have changed the implementation a little instead by getting the source code of the decryptFromIpfs function and put it in my custom function, replaced the code of getting the symmetric key to the following which is the normal way to get the symmetric key, but seems like I am getting the 500 error like the following, want to know how this issue can occur:

      const symmetricKey = await window.litNodeClient.getEncryptionKey({
        accessControlConditions: metadata.accessControlConditions,
        toDecrypt: metadata.encryptedSymmetricKeyString,
        chain,
        authSig,
      });

Error:

POST https://node2.litgateway.com:7371/web/encryption/retrieve 500 (Internal Server Error)

The code implementation of using the code extracted from the decryptFromIpfs can be found here: https://github.com/Eric1015/lit-encrypt-decrypt-file/tree/feature/extracted-version

Example file uploaded to IPFS: https://ipfs.io/ipfs/QmRCfFASmzJ2EfdBemdj59yY8rkEbghAfamqZ4TCia5EuU

I actually figured this out myself. I have chosen to use the serrano developer network for now. Although I know the contents uploaded there is subject to deletion, but for my personal project, I can tolerate this.

I don't know if anything additional is required in the mainnet, but according to the official document, the mainnet is in alpha state and that might be the reason why it does not function well enough to support my use case at this moment.

I believe, Your accessControlConditions are incorrect, which is why you (yourself) do not have permission to access the data and will see an error.

see below example:

const yourEthAddress = 'xxxxxxxxxx'
const accessControlConditions = [
  {
    contractAddress: '',
    standardContractType: '',
    chain: chain,
    method: '',
    parameters: [
      ':userAddress',
    ],
    returnValueTest: {
      comparator: '=',
      value: adminEthAddress
    }
  }
]

const ipfsCid = await litNodeClientNodejs.encryptToIpfs({
    authSig: authSigVal,
    chain: chain,
    string: stringForEncryption,
    litNodeClient: litNodeClient,
    accessControlConditions: accessControlConditions,
    infuraId: infuraId,
    infuraSecretKey: infuraSecretKey,
})

const str = await litNodeClientNodejs.decryptFromIpfs({
  authSig: authSigVal,
  ipfsCid: ipfsCid,
  litNodeClient: litNodeClient
})
console.log("[str] ", str)

It will be working fine :)

Hum, yeah seems like you are right.
I also made that change in my second try along with the network change, so I didn't notice it.

Thank you for the information, closing this issue.
