Hi, I have identified an issue with JuliaInXL by the time to follow the provided [tutorial](https://youtu.be/59Kr37uqtm4) at minute 10:50.  
I am trying to create a function in the REPL as simple as:

```julia
mm2(x) = x + 2 # as same as the video suggests 

```

However this error message appears:

and in the excel, appears this message

Here are the specs for the package used along with Julia 1.7.2

I have been following several cases which have solved this issue by “parse-ing” or “eval-ing” the inputs, however, although these solutions work fine in the REPL, using them in the Excel file still are generating this error. Please, could you help me with that?

Regards

Hi @ameresv!

In all honesty, I am quite surprised that this package works at all.  
That video you linked is from 2017 and before Julia 1.0 was even released.  
Generally, I have run into this issue in the past when you try to conditionally load/export functions or change the running state of Julia in some unexpected way.  
I do not know really what is happening other than I can see that the error is originating from JuliaWebAPI…

Can any JuliaComputing folks take a look at this as it is hosted by JC?

Sorry I couldn’t be more helpful.

P.S. Also, try opening an issue on the repository as well with the errors you are getting and every step you took to get to this blocking point.  
Might get some more feedback there! 😃

Thanks a lot, Jacob. I will also try to reach the author to learn more about the chance to embed my Julia code to excel.
