Getting Started README example doesn't display data.

I am following the Quick Start with Docker section
It built and I am able to see the web UI.
I am not sure if I am erroring out on the last step (Run your first simulation) but I don't see anything being populated on web UI.

This is what I see in the logs:

forefire> listenHTTP[]
ForeFire HTTP command server listening at http://localhost:8000
To stop the server, press Ctrl-C or type quit in the ForeFire shell.

Hi @iperezx

You need to type include[real_case.ff]
and send it, this makes forefire simulate the event. Indeed nothing appears at this moment

But after that you need to press the button "Refresh Map" the simulation appears..

But i understand this can be a bit tricky so we'll think of a way to explain better on readme or maybe change the button color to make it stand more

Hi @iperezx and thanks @antonio-leblanc

Yes.. the GUI is more of a shortcut to an interpreter, you may even actually launch include and the listenHTTP,
Actually I kept the fact to "refresh map" because "refresh map" is actually also a command.
so that the interface itself is like a way to understand the philosophy (everything is a command/instruction).. somehow problem is that quick start is not totally possible... would need a bit more..

Maybe we can change the "quick start" to state:
"everything is command in ForeFire, open browser, then click "include" button to pre-write the include[realcase.ff] command, then "send" then "refresh" to launch the "print[output.json]" command that is linked to update the display.
what do you think @iperezx ??

also, the html interface is highly customizable, it is complimentary to ForeFire, more a showcase of what would be possible to do the we'll have a nice community making plenty of interfaces in 2D/3D.. ensembles... AI..

hi @iperezx , thanks to @antonio-leblanc, this has been addressed, much less 404 in the console too.
Is it OK to close the issue ?

[iperezx]

Thx! I pulled in your guys new changes.
After typing the following in the command text box and pressing the send button:

include[real_case.ff]

I see this error in the UI:

forefire >include[real_case.ff]
Problem Loading data from NetCDF file /forefire/tests/runff/./data.nc: NetCDF: Unknown file format
file: ncFile.cpp  line:88
Exception in creating a_time: std::bad_alloc

On the command line interface I see the following:

forefire> NetCDF: Unknown file format
file: ncFile.cpp  line:88

@iperezx
please can you provide more info on the setup you are running?

• what is the OS
• Are you using the docker right?
• What version of forefire appears when launching

it will help on the debug here thanks

hi @iperezx
Also, can you check the file size of /forefire/tests/runff/./data.nc or if it exist whatsoever, it should be about 4Mb but some users has issues related to their configuration of gitLFS.

[iperezx]

Hi all,

I am following your guys README(the instructions for Docker: https://github.com/forefireAPI/forefire?tab=readme-ov-file#quick-start-with-docker)

/forefire/tests/runff/data.nc is not 4MB. its 1328 Bytes

I am on Apple Silicon.

forefire version:

I was trying to change the docker build platform to see if that might fixed things:

docker build --platform linux/amd64 . -t forefire:latest

But I get build errors coming from https://github.com/forefireAPI/forefire/blob/master/Dockerfile#L25
