Lua programming

[Relaxandbecool 1]

I am doing something really silly, but cant find the answer.

 

Everytime I try to call a function I get some nil reference error, like for HTTPClient or getDeviceIds or anything. So some setup is wrong, but I cant find the answer. Even if I try to put “require” somewhere I get a nl reference error on that call ...

 

Pointers much appreciated.

The Lua we have on HC2/HC3 devices is limited - some standard Lua functions are removed. 'require' is such a function (in fact, if you call 'require' you would get an error, not nil)

net.HTTPClient():request(...) works with callbacks, so the function returns nil but it will call your provided 'success' and 'error' functions when it gets a result.

There are many discussions on this in the forum - try the search function.

Many thanks. Yes, I am trying to follow API documentation, sample code examples (for example from Tinman) and others, but every function that is called seems to produce some error message saying attempt to call a nil function or some such error. The API docs refers to require so its interesting to know that its not implemented. For a newbie trying to find accurate information it sure is hard .....
