Array of cloud credentials, along with path matching regex strings - Required if any files in the masters are cloud references (currently only AWS S3 is supported)

  • If this parameter is non-empty, all items in fileInfo are assumed to be items in cloud storage
  • Format: [
  •       {

  •         path_matchers: ["FILE_PATH_MATCH_REGEX_1", "FILE_PATH_MATCH_REGEX_2" ...],

  •         remote_access: {

  •           protocol: "s3",

  •           platform: "aws",

  •           path: "YOUR_AWS_S3_BUCKET_NAME" + "/",

  •           storage_endpoint: {

  •             region: "YOUR_AWS_REGION_NAME"

  •         }

  •       },

  •       ...

  •     ]
  • The simplest case is a one element array with .path_matchers == [".*"], in which case the same credentials will be used for all items in fileInfo
Throws:

error - If the initialization of the master fails, error details can be found in error.body

Finalize a mezzanine object after all jobs have finished

Returns: The finalize response for the mezzanine object, as well as any logs, warnings and errors from the finalization
Parameters:
Name Type Attributes Description
libraryId string

ID of the mezzanine library
objectId string

ID of the mezzanine object
