Scenario description: A position is known to exist in the system, but it cannot be found when it is uploaded in the system
Reason analysis:
This position has been closed/suspended: the default display on the upload resume interface is "Show published positions", which can be adjusted to "Show all positions" to confirm whether you can select this position
Do not have the processing rights of the position: is not the position of the position of the collaborators, if you need to add the position of the collaborators can be modified internally and then added to the position of the collaborators
Post status is draft or Ready to publish: Posts in draft and ready to publish status cannot be displayed, even if all posts are selected
