@huangshayang I see you’ve also raised the same issue on the Spring Framework issue tracker. Please do not cross-post bug reports as it means two different team members can end up duplicating effort

I use the Spring rsocket 2.6.3 and the mongo gridfs for backend and the rsocket.js in browser .

At first The spring works properly in requestchannel mode , but after version 2.5 of the spring boot not works properly .

for uploading first media has been broken to many chunks . per chunk has 8kb size then i send per chunk by Flowable . the first chunk has been sent by the javascript and backend receive it , but the second chunk has not been received by the spring . this problem has been created after version 2.5 of the spring
