Problem with job /solutions/racket

What happens

I’m trying to upload the solution to a challenge on racket language but the pipeline solution/racket gives an error.

What do you understand or find about that problem

the pipeline in the line 430 says: line 12: envtarget: unbound variable, but the problem is not in mi script because when i run the script it give me the right output, so i dont understand where is the problem

Did you try any workaround? What did you do?

i dont know what to do

I want to know how else I can solve the error, since I don’t know what my error is
