Error Lookup
This page provides a list of errors that may be returned by the Janus API, within the "details" array. In some cases, the errors will be provided outside of a standard details array, if the error occurs before reaching the API backend (for example, if the input body is not valid JSON). During processing, Janus appends to the details array in order, and the first error in the array will generally describe the error most accurately. The following tables can be used as a reference for solving common errors. Note that this list may be incomplete as new error messages are added to the API on a regular basis.
