Race condition when running create API

[halalpractitioner]

Hi fellow Bubblers,

I’m working with an API that allows creating multiple sub-members under a single super member. Each super member is allowed a maximum of 2 sub-members.

I’ve already implemented logic to check if a super member has 2 or more sub-members and terminate the workflow in that case. However, this doesn’t seem to work properly when a super member opens multiple devices or tabs and tries to create sub-members at the same time — sometimes it still ends up creating more than 2.

(See attached image for context.)

How can I fix this concurrency issue to ensure a super member can’t exceed the limit, even with simultaneous requests?

Many thanks in advance!

The generation uses the content of the previous sections to prompt the generation of the current section. Users can generate each section one by one, and they should be able to generate multiple at a time (so if they click generate on sections A, B, and C, section A will be generated, then section B, then section C, rather tha…
