The WEDIA error code followed by the error message (as it appears to the end user in production mode (without contextual/debug details))

The main types of errors, giving information on the type of problem (an invalid parameter value, a configuration problem, a security problem...).

The HTTP code (status) of the error

The circumstances or conditions under which the error occurs, or the causes of the error.
On the right, icons indicate when :

• the message displayed in production is different from the one displayed in development/debug mode (the messages displayed in production are generally vague, while those displayed in debug mode are contextualized to facilitate debugging);

• the main message is supplemented by a more precise secondary message on the circumstances of the error (in this case, it is described in additional information in the documentation, between 5 and 6);

• the message contains an invitation to contact an administrator (this is an error that cannot be corrected by the API consumer, and requires either the intervention of an administrator or the intervention of Project Services);

• the error has an error sub-code specifying more precisely the type of error.

Optionally, more precise explanations on the circumstances or conditions with possibly indications on how to solve it (for example, if the problem comes from security, or from a configuration, or if it is up to the consumer to provide a missing parameter, etc).
