AccessControlAllowHeaders is not defined

Hello people,
I downloaded the 2020 version and it presents the following error in the generation:

Generating Api.php…
undefined:14
let allowHeaders = AccessControlAllowHeaders;
^
ReferenceError: AccessControlAllowHeaders is not defined
at eval (eval at compile (C:\Program Files (x86)\PHPMaker 2020\node\node_modules\phpmaker\phpmaker.js:7:5518), :14:21)

Generation completed, please scroll up (if necessary) to check error(s) highlighted in red.


I consulted the documentation and found no reference to the error.
Can you help me?
Thank you

Make sure you use the latest version (v2020.0.15).

After uninstalling and deleting all traces of PHPMkaker, I was able to generate the application.
Now, when I run, the following message appears:
Composer generated autoload.php does not exist. Make sure you have run “composer update” at the destionation folder on your development computer and uploaded the “vendor” subfolder.
I did all the procedures indicated for installing the composer.

Make sure you have run composer update and upload the “vendor” folder, read this first if you do not know what composer is: https://discourse.hkvstore.com/t/migrating-to-v2022/655/1

thank you all
