mimeType
Store a MIME type with the variable. If left undefined, it will default to application/json. Two specific MIME types cause this state to behave differently: text/plain and application/octet-stream. If the value evaluates to a JSON string the MIME type is text/plain, that string will be stored in plaintext (without JSON quotes and escapes). If if the value is a JSON string containing base64 encoded data and the MIME type is application/octet-stream, the base64 data will be decoded and stored as binary data.
