When GS follow follow request enabled Misskey account.
Misskey has following error. And GS cannot feed Misskey's posts (followed dummy account).

This log is tried following email@example.com to firstname.lastname@example.org.
requestId seems to be following.
https://example.com/follows/<from ID>/<to ID>
https://example.com/follow_from_<actor URI>_to_<actor URI>
GS's requestId seems to be too long. If GS's requestId is shorten, this problem will be fixed.
Misskey can enable follow request by [Settings]-[Privacy]-[Follow requests require approval].
This was actually fixed in v3, but for sheer luck. Thank you for noticing and reporting this.
