Sync is not working without

The scheduler throws an error if the checkbox “Delete file, if the file does not exist in the mediaspace” is not activated and a file is deleted in the mediaspace.

Client error: `GET https://....px.media/gobackend/files?pageSize=20&page=1&responseFields=%5B%22metadataFields%22%2C%22id%22%2C%22subject%22%2C%22description%22%2C%22originalFileURL%22%2C%22previewFileURL%22%2C%22location%22%2C%22keywords%22%2C%22rating%22%2C%22createDate%22%2C%22modifyDate%22%2C%22colorspace%22%2C%22creator%22%5D&filter=%7B%22filterType%22%3A%22files%22%2C%22fileIDs%22%3A%5B1154963483%5D%7D` resulted in a `404 Not Found` response: {"success":false,"errorGroup":"unknown","errorcode":2454,"errormessage":"The specified file ID does not exist."}

Before querying the file, a check must be made to see whether the files still exist. The filesCheckExistence API must be used for this.
