Error: AnchorError: AnchorError caused by account: base_account. Error Code: AccountNotInitialized

Question

I wrote a Solana Program with two functions, one for the initialization of an account and a second to upload data to the account. While testing on localhost it was working fine, but when I uploaded it to Devnet I get the following error:

Error: AnchorError: AnchorError caused by account: base_account. Error Code: AccountNotInitialized. Error Number: 3012. Error Message: The program expected this account to be already initialized.

      at async file:///C:/Development/SmartHealth/smarthealth_js/index.js:131:28

The error comes up only when I try to upload the data and sometimes it doesn't come up at all and the data gets uploaded successfully to the account. I am not sure why I am getting this error sometimes. Can someone please tell me what is the problem?

Below is the JS code through which I am calling the Solana program functions:

const tx = await program.rpc.initialize({
        accounts:{
            baseAccount: baseAccount.publicKey,
            user:provider.wallet.publicKey,
            systemProgram: SystemProgram.programId,
        },
        signers: [baseAccount]
    }).catch((err)=>{
        console.log(err)
        return {"Error":err}
    });

console.log('New Base Account Generated: ',baseAccount.publicKey.toString());
console.log("Transaction Signature: ",tx);

const timestamp = new Date().toUTCString()
    const uploadTx = await program.rpc.uploadRecord(pid,did,title,file_id,timestamp,{
        accounts: {
            baseAccount: baseAccount.publicKey,
            user:provider.wallet.publicKey,
        },
    }).catch((err)=>{
        console.log(err)
        return {"Error":err}
    });

I have even tried keeping the pid,did, title,file_id values the same but still I get the error sometimes. Even the account gets generated as I get the transaction signature for that on the console but data doesn't get uploaded.

Instead of running these one after the other or adding a delay between them, but both instructions into the same transaction. E.g.:

  let tx = new Transaction();
  tx.add(await program.methods.initialize(....).instruction());
  tx.add(await program.methods.uploadRecord(....).instruction());
  await program.provider.sendAndConfirm(tx, [baseAccount]);

This way the account is always created when you go to call upload, because it will be created earlier within the same tx.
