TypeError: Cannot read properties of undefined (reading 'varType')

[LSarribouette]

Hi all,

We are progressively compiling more and more complex models until having our complete model running, dealing with the errors one at a time. It seems all our XLSX calls work now and we now have a TypeError.

We get this error both when we run npm create @sdeverywhere (but we kept going since we got the message 'The mdl file failed to load (...) diagnose the issue later.') and then npm run dev.

What do you think? Do you have a simple way to find which variable is causing trouble?

Here is the full error:

Hi @LSarribouette, sorry for the trouble. In general the compiler will normally include details in the error message when there is an issue with a specific variable, but in this case unfortunately there is not. This looks to be a case where an error isn't expected, and I'm not sure yet what's causing it.

Is your model (or some subset of it that might be triggering the issue) open source by any chance? If I had access to the mdl files, that would be the easiest way for me to diagnose, but I totally understand if you're not able to share your model openly (or even privately).

If not, the next thing to try would be to add some logging to the compiler to help debug. Unfortunately where it's failing is earlier than some existing logging code, so we can't rely on that existing code. I made a temporary build to help you diagnose (see this branch diff for the code change). To use it, change your package.json as follows to use the temporary build (be sure to run npm i once after changing the file):

diff --git a/package.json b/package.json

     "@sdeverywhere/plugin-vite": "^0.1.8",

If you npm run dev or npm run build, it should print out some debug information that might shed some light on the error you're seeing. The code is failing to resolve a variable referenced by another variable. Hopefully you will see a line that starts with "ERROR", and that might point you to the variable(s) that are triggering the issue. If you send me some portions of the log and mdl, I might be able to help diagnose.

Or, if you don't mind going deeper and making changes to the compiler to see what else is going wrong, you can clone the SDEverywhere repo and change your package.json to point to your local version of the cli and compile packages, like this (again, be sure to run npm i once after changing the file):
