hi, my code like this:

const xsysAccount = getPDA(program, SYS_ACCOUNT_SEEDS)

return program.account.sysAccount.fetchAndContext(xsysAccount)
.then((xdata) => {
    console.log(`sysAccount: `, xdata.data)

    return true
})
.catch((xerr) => {
    console.log(`callGetData fail: `, xerr)

    throw xerr
})

when run it, it throw a exception, the exception is:

StructError: Expected the value to satisfy a union of type | type, but received: [object Object]
