Problem sit master composer.json

[Giuliano69]

Hi, thaks for your extenstion.
I was trying to install, but failed due to an errror in master composer.json.

It fails at step 4) claiming
[Composer\Repository\InvalidRepositoryException]
No valid composer.json was found in any branch or tag of https://github.com/emizentech/magento2-price-slider/, could not load a package from it.

I enclose verbose install:

1. modified composer.json in magentoRootDir to update "minimum-stability": "dev"
   "version": "2.3.5-p1",
   "minimum-stability": "dev",

2. magento_user@firenze:/var/www/penstore$ composer clear-cache

Cache directory does not exist (cache-vcs-dir): Clearing cache (cache-repo-dir): /home/magento_user/.cache/composer/repo Clearing cache (cache-files-dir): /home/magento_user/.cache/composer/files Clearing cache (cache-dir): /home/magento_user/.cache/composer All caches cleared.

3. magento_user@firenze:/var/www/penstore$ composer config repositories.emizentech-magento2-price-slider vcs https://github.com/emizentech/magento2-price-slider/ -vvv
