GitHub REST API Client v0.2.0

View Source GitHub.Error exception (GitHub REST API Client v0.2.0)

Exception struct used for communicating errors from the client

Note

Functions in this module is unlikely to be used directly by applications. Instead, they are useful for plugins. See GitHub.Plugin for more information.

This error covers errors generated by the client (for example, HTTP connection errors) as well as errors returned from the GitHub API (for example, Not Found errors).

fields

 Fields

  • code (integer): Status code of the API response, if a response was received.

  • message (string): Human-readable message describing the error. Defaults to a generic "Unknown Error".

  • operation (t:Operation.t/0): Operation at the time of the error.

  • reason (atom): Easily-matched atom for common errors, like :not_found. Defaults to a generic :error. See Error Reasons below for a list of possible values.

  • source (term): Cause of the error. This could be an operation, an API error response, or something else.

  • stacktrace (Exception.stacktrace/0): Stacktrace from the time of the error. Defaults to a stack that terminates with the calling function, but can be overridden (for example, if a __STACKTRACE__ is available in a rescue block).

  • step (plugin): Plugin active at the time of the error (expressed as a tuple containing the module and function).

Users of the library can match on the information in the code and source fields to extract additional information.

error-reasons

 Error Reasons

Although plugins may use any atom for the reason field, the following have predetermined meanings:

  • :invalid_auth: The credential (:auth option) provided is invalid.

  • :invalid_version: The version (:version option) provided is invalid.

  • :not_found: A resource or route was not found. Note that GitHub may return this kind of response when authentication is required to see a resource.

  • :oauth_restricted: The OAuth credentials are valid, but the requested resource is owned by an organization that requires admin approval for OAuth apps.

  • :rate_limited: The client has exceeded a primary or secondary rate limit. Secondary rate limits have a distinct message field with further information.

  • :requires_auth: The requested endpoint requires an authenticated user, and no auth credentials were given.

  • :unauthorized: Valid authentication credentials were given, but the current user does not have permission to perform this action.

The current stacktrace is automatically filled in to the resulting error. Callers should specify the status code (if available), a message, the original operation, the source of the error, and which step or plugin is currently active.
