Error initializing generated capabilities during a test run

[Niels Roche]

If I start a test with capabilities I get the following error message:

PS Q:\repos\smartthings_edge_drivers> lua54 "Q:\repos\SmartThingsEdgeDrivers\drivers\SmartThings\zigbee-contact\src\test\test_zigbee_contact_battery.lua"

it's a test from the public zigbee contact drivers.

Same error I got, running my own driver tests ...

seem it's happening during calling st.capabilities.[CAPABILITY_NAME] ...

I've changed capabilities/init.lua inline_type_schema(schema) to this:

inline_type_schema = function(schema)
  if schema["$ref"] ~= nil then
    local type_name = schema["$ref"]
    if type_name == "color-map" then
      type_name = "COLOR_MAP"
    end
    local cap_type_ref = require(string.format("st.capabilities.generated.types.%s", type_name))
    -- TODO: Should this be a separate RPC call or inlined upstream (rust?, cloud?)
    return inline_type_schema(json.decode(cap_type_ref))
  end
  local out_schema = {}
  for k,v in pairs(schema) do
    if type(v) == "table" then
      out_schema[k] = inline_type_schema(v)
    else
      out_schema[k] = v
    end
  end
  return out_schema
end

seems to work ...

This is typically caused by running with lua 5.4, all SmartThings drivers run and expect lua 5.3
