What causes the occurrence of [Object object] instead of a memo being displayed when the memo is included in the transaction building process in Stellar

Having trouble adding a memo to a wallet generated on the Stellar network, encountering an XDR write error in the SDK.

Error stack trace:

      .createAccount(createdAccountKeyPair)
      .setMemo(new Memo(MemoText, 'test-memo'))
      .build();

Input provided:

    const createTxn = txBuilder

Answer №1

To properly execute the task, follow these steps:

setMemo(new Memo("text", "Memo string"))

Using MemoText as the initial parameter is incorrect; it should be a string as per the guidelines provided in the documentation.

During the construction of the error message, it appears that MemoText.toString() is being executed, resulting in the printing of [Object object].
