Here's a minimal example that reproduces this: https://github.com/chrisguitarguy/rie-init-error-example (./run_example there should do it).

Seems to originate from here:

aws-lambda-runtime-interface-emulator/lambda/rapidcore/server.go

Line 223 in 00d793b

return fmt.Errorf("ReplyStream not available")

There are some additional warnings that show up too:

time="2021-04-28T14:07:35.64" level=warning msg="Failed to send default error response: ErrInvalidInvokeID"
time="2021-04-28T14:07:35.64" level=error msg="INIT DONE failed: Runtime.ExitError"
time="2021-04-28T14:07:35.641" level=warning msg="Reset initiated: ReserveFail"

Looking at that server.go, it seems like it all depends on invokeCtx being set, but that wouldn't be set up for init errors given there is not invoke context yet -- something went wrong before it go to that point, right?
