Dropbox Community ModeratorThanks for the report. For clarity though, can you also share the code and parameter values you're using, e.g., for filesListFolder, filesListFolderContinue, and filesListFolderLongpoll? That would help make sure we investigate the right scenario.
Also, when you say this "results in a false positive change-loop", do you mean you're getting stuck in a `changes:true` -> ` "entries": [], ...,"has_more": false` infinite loop, or does that happen just once per change?
Sure! Here's how I repro'd it on my side:
I called https://dropbox.github.io/dropbox-api-v2-explorer/#files_list_folder/get_latest_cursor
with path: "/Apps/Songbook.Studio/Library" (if you need ids from me instead let me know)
then I called https://dropbox.github.io/dropbox-api-v2-explorer/#files_list_folder/longpoll
with cursor: "AAHYcbsJjEIIcObeUpf7Uu9QgkTFe0-6zAH3f43ypSgDm035GKew13WormET99lOBzz9Z9HCKOEapDe_Gp4fCP0TqDKb_FF6yHe6RnACghIQJSa7XT4HrKj2wKFvAFsWOl89bqvtBD0VYZ4JPvGzpmuSJ_xyjFjJH9-SnkxRe7Q0148beWvf71Jk68ukBNnsawn7jutFHLzS82LzJhA4y4z2fNjMvTx9yB8c61gakAVkGhG7v73CsiFpNNHfcxzbqpE"
it sits and spins...
I went to the Dropbox web UI and dragged/dropped a test image file (foo.png) into the parent folder: "/Apps/Songbook.Studio"
the longpoll returns with `changes: true` at this point
I call https://dropbox.github.io/dropbox-api-v2-explorer/#files_list_folder/continue
with cursor: "AAHYcbsJjEIIcObeUpf7Uu9QgkTFe0-6zAH3f43ypSgDm035GKew13WormET99lOBzz9Z9HCKOEapDe_Gp4fCP0TqDKb_FF6yHe6RnACghIQJSa7XT4HrKj2wKFvAFsWOl89bqvtBD0VYZ4JPvGzpmuSJ_xyjFjJH9-SnkxRe7Q0148beWvf71Jk68ukBNnsawn7jutFHLzS82LzJhA4y4z2fNjMvTx9yB8c61gakAVkGhG7v73CsiFpNNHfcxzbqpE"
and the response is:
{ "entries": [], "cursor": "AAHp_o9htUtsuvBy6ZLjlTyxIetGJZKp64hcFe641rOod28dbdiXDDw18CXg4T1DtBXDPexxpdzO9K8x8s7iX6YDB6XLcyzAJCPwb5xQuXSyXEbnjOEptD1xNvCUAG0hxxnWN5TgPl3fd-urlcaMtmzvt-0rVRg-RmKxJsbgp_7cKMrccWDoodbQFmNe2DrvY0nSgedfTcMxzWktRANN0hP8zzsv9uXrR4vZgoNaYPEv7BKQLZgdgBCiZHJvV1__tQ4h0AOpFvFK67An_KMgMgJwDZMQ7DnckIBAfoboOrJm5g", "has_more": false }
What I mean by the loop in my situation is that everytime I get a new cursor I update a file "/Apps/Songbook.Studio/.preferences.json" as my "durable storage" for the user's last update. When I do that, it triggers the longpoll's to return with the cycle described, so I have a kind of infinite back and forth.
