FlexSim Webserver Uploading Model

Is that a valid path for the model directory? You have an account whose user name is 'username' ?

Although it is rewritten as "username" to hide my user name, the correct user name and Model Directory are set in the actual configuration.

The gif shows selecting the model in that directory and running the instance.

If the model is successfully uploaded, the model will be added to the Model Directory, right?

What permissions does the user directory have? Are you running IIS or the executable webserver?

I found three issues:

I was unable to open a model using the webserver using FlexSim 2024 Update 1. Only Update 2 seems to work. I wonder if we fixed some bugs that broke compatibility with 24.1.

In server.js, the following line needs to be changed:

// remove "new" from this line, near 464
busboy = Busboy({ headers: req.headers });

In queryhandlers.js, the following line needs to be changed:

// add .filename after file.name, near 337
file.mv(settings.general.modelDirectory + '/' + file.name.filename, function(err) {

After making those changes, I was able to upload and run a model. I'll add this question to the dev list so we can make these changes for everyone. @Jacob Gillespie may have more/better information.
