Load test using Shinycannon fails Playback failed: receiveQueue is full (max = 5)

Hi All,

I'm trying to run a load test for a shiny app deployed to RSC.

I recorded the log using shinyloadtest, and trying to run the simulation using shinyconnon.

Unfortunately this fails:

I'm running this on Ubuntu 20.04.

I tried to google the error but no luck, so maybe someone here could help me.
Thank you.
