Understanding error message

[njirvine]

Hi there

This feels really basic but I am getting nowhere searching online for an interpretations. I'm struggling to interpret where my error is with my model.

nlrx all works well for the wolf-sheep sample given. So thought i would try my model, but when I run i get:

Run #1, JAVA EXCEPTION: Expected reporter. Expected reporter. at position 49

I assume its a problem with my model code interacting with nlrx, but i'm struggling to know where it is pointing me to - how do i know what position 49 is so i can find the exact error point?

model works fine in netlogo so all netlogo reporters are in place and working well

Thanks

Hm, this is just a shot in the dark, but nlrx internally uses netlogo-headless and on https://github.com/NetLogo/NetLogo/wiki/Controlling-API it says:

When running headless, there are some restrictions:

The movie- primitives are not available; trying to use them will cause an exception. user- primitives which query the user for input, such as user-yes-or-no will cause an exception.

Do you use any of these?

Position 49 should refer to line 49 of your code. You can open the file in a proper editor (atom, notepad++, visual code, ...) with line numbering so you don't have to count lines by hand.

Thanks again :)

No movies and no user prompts (all removed for verification/validation) and the experiment code sets the user input values as per the nlrx instuctions.

Line 49 is in the global variables list. Its a big model and a hybrid ABM/DES so the globals list is about 300lines long

I do use the time extension but the link-up for the date/time output is in the set-up. The 49th line in the setup is reset-ticks so not that.

:/

Update. It's fixed. You were on right on the nose about the user commands. I thought i had removed them all, but i had wrongly tried to code them into the experiment script.

                            outpath=outpath,
                            repetition=1,
                            tickmetrics="true",
                            idsetup="setup",
                            "allocate-expert",
                            "allocate-trainee-shift",
                            "allocate-senior-nurse",
                            idgo="go",
                            runtime=56001,

the allocate commands are the user ones. Reviewing the nl object I noticed that the allocate commands had been assigned as other conditions.

ive coded them directly into the model at setup and now it works.

Thanks again :)

Glad to hear that :-)
