statuscode:501,"message":unable to save changes made outside the editor to ContentID(id=0)

When I tried to used RESTAPI to request and post to confluence page, the error is

statuscode:501,"message":unable to save changes made outside the editor to ContentID(id=0) while collaborative editing is disabled.

Any one can tell me what happened and how to solve this problem? Very urgent to solve this issue. Thanks for help!

You need to enable collaborative editing to edit the doc. If it is already activated, delete the plugin cache and retry.

See https://confluence.atlassian.com/doc/collaborative-editing-858771779.html and https://confluence.atlassian.com/confkb/how-to-clear-confluence-plugins-cache-297664846.html for reference.
