Error Codes

Radiccio uses the set of standard OpenSubsonic error codes.

In addition, Radiccio uses some custom error codes, which are listed below.

All nonstandard, Radiccio-specific error codes have the vendor prefix 3264, which is the default port number that Radiccio Server runs on. This is to avoid potential overlap with future OpenSubsonic error codes.

Code Description Additional info
326471 This server does not implement the requested endpoint. For various reasons, many OpenSubsonic servers only implement a subset of the base set of endpoints.

Unfortunately, the OpenSubsonic spec does not specify any particular behavior for unimplemented endpoints, so we have created our own code so that you can detect this situation with Radiccio Servers. Other servers are likely to handle this situation differently.

You should not use this code to check for endpoints associated with an extension. Check for the presence or absence of the extension in getOpenSubsonicExtensions instead.

If you attempt to access an unimplemented endpoint that is not defined in the base set of OpenSubsonic endpoints, the server responds with an HTTP 404 error instead. The OpenSubsonic spec is unlikely to expand the base set in the future, because they use extensions for that purpose instead.
3264101 The system Keychain is locked. There was an issue accessing the macOS Keychain, which means Radiccio Server is unable to authenticate any clients, and therefore cannot respond normally to API requests.

This should not normally happen. The user should contact Radiccio support for assistance.
3264102 This endpoint is only available in JSON. For compatibility with older player-clients, Radiccio provides the basic OpenSubsonic endpoints in XML as defined in the spec. However, it takes a lot of extra time and effort to support both JSON and XML, and almost all newer clients use JSON. As such, we do not provide any Radiccio-specific functionality in XML. If you are making a new client, please use JSON.
3264103 Key pair authentication failure Internal Radiccio use - does not apply to non-Radiccio clients.
