Problem

What do the Node Manager error codes mean? For example, the 102 in the following error message:

Error code: 102.

Resolution

These numbers just classify the error according to the type of error object that holds the error. They're not actually all that meaningful. The codes themselves are defined as follows:

GENERIC_ERROR = 100
VALIDATION_ERROR = 101
SERVER_ERROR = 102
CONFLICT_ERROR = 103

These refer to whether a ValidationError, ConflictError, etc. object was created. There should be a message prior to that error with more useful information, usually something such as: "error occurred on call from Node Manager on 'example.com' to https://example.com:8090' for URL '/api' and 'GET'"
