Task exception - Githubissues

Hello!

On your advice, I have rebuilt my system on tasks. Now the simulation main loop runs in its own task. In the block (module) 'ShowSubSystem' there is only a print(sim.timeS) in the block.step () function. block.start() is empty. Below is the source code. Interestingly, the simlation does two steps bevor the error appears (Start, Step 0, Step 0.1). What am I doing wrong?

sim = {
  assert = function(block, ok, message)
    assert(ok, message)
  end,
  stepRateS = 0.1,
  timeS = 0,
  step = 0,
  stepT0 = 0,
}

block = {
  ellapsedS = 0.1
}

block.ShowSubSystem = require 'ShowSubSystem' -- 0
block.ShowSubSystem.parent = block
block.start = block.ShowSubSystem.start
block.step = block.ShowSubSystem.step

block.start()
-- Main simulation loop
do
  if nvs.exists('p+', 'crash') then
    print('[p+] Crash detected:', nvs.read('p+', 'crash'))
    nvs.rm('p+', 'crash')
    os.rename('./startup.lua', './startup.old')
    while true do tmr.sleep(1) end
  else
    print('[p+] Start  simulation ' .. (sim.stepRateS * 1000) .. 'ms cycle time')
    nvs.write('p+', 'crash', true)
    block.start()
    local t = tmr.attach(
      math.floor(sim.stepRateS * 1000),
      function()
        block.step()
        collectgarbage()
        sim.step = sim.step + 1
        sim.stepT0 = sim.stepT0 + 1
        sim.timeS = sim.timeS + sim.stepRateS
        if nvs.exists('p+', 'crash') then
          nvs.rm('p+', 'crash')
        end
      end
    )
    t:start()
    while true do tmr.sleep(1) end
  end
end
