Hi,
We are sorry you encountered this problem.
In order for us to help you we need instructions on how to reproduce the problem. It would help if you send us a NetLogo model (ideally not too complex) and instructions for how to reproduce the issue.

Because Github does not accept files with the extension .nlogo if you do send a model either 1) send it inside a zip file, or 2) change the name to have an acceptable extension such as .txt.

I am experiencing a similar error (copied at the end of this comment). In my case, loading an exported world through import-a:world coupled with fetch:url led to the issue when using the NetLogo local app. This error happens after loading the imported world's agents and their parameters into NetLogo. So, for my implementation (shown in detail below with attached files) the model would function properly after the error is displayed as long as I manually execute the required function because the error stops NetLogo from executing a sequence of commands.

For replicating the process, I am attaching the following:

1. A NetLogo file with the setup button importing worlds from this online repository. Please modify the extension to .nlogo to open the file properly. [ABM_import-a_error.txt]
2. The world file that leads to the error (error world) [S19.0.16_world_300years_3monthsTick_error.csv]
3. The world file that does not lead to the error (clean world) [S19.0.16_world_300years_3monthsTick_clean.csv]

To import the "error world" using import-a:world from a URL, open the NetLogo file and set the Baseline-type input as "3-month step (ERROR)" then press the Setup button. This will import all the agents and their parameters, but it will not create any drawn lines. At this state, I re-exported the world and labelled it as "clean world". Interestingly, loading the exported "clean world" through setting the Baseline-type input as "3-month step" does not lead to any errors.

As I mentioned previously, the key difference that I can observe between the "error world" and the "clean world" is that the former includes information about the required lines to draw (which I assume is causing the error). I may be missing something here, but I thought reporting the error alongside my observations can be useful.

Here is the error:
