error: invalid version byte. expected 48, got 16 trying to authorizeEntry

[kalepail]

Describe the bug

When trying to authorizeEntry I'm getting an error:

356 |   var expectedVersion = versionBytes[versionByteName];
357 |   if (expectedVersion === undefined) {
358 |     throw new Error("".concat(versionByteName, " is not a valid version byte name. ") + "Expected one of ".concat(Object.keys(versionBytes).join(', ')));
359 |   }
360 |   if (versionByte !== expectedVersion) {
361 |     throw new Error("invalid version byte. expected ".concat(expectedVersion, ", got ").concat(versionByte));
                ^

Bun v1.1.8 (macOS arm64)

What version are you on?

"@stellar/stellar-sdk": "^12.2.0",

Expected behavior

The auth entry should get signed
