Consequent API calls failed

See original GitHub issue

I’ve used some Python script from which I did API requests to Eclair node. I needed generating new invoices.

In every second consequent calls I got such error. After second call, if i tried to request node it returned expected result (with invoice) or error (if request is malformed).

@t-bast report.

I’ve built custom Python script reproducing basically similar requests to Eclair node and set it up with various sleeping times between consequent requests. The shortest interval I’ve tested is pause = 0.001 #second and Eclair didn’t show any error related to this issue.

Thus, I’m closing it. Thank you for your work.
