Hello,

I have librenms running almost fine since 2 years, but since few days
When running validate.php as cli:

librenms@librenms:~$ ./validate.php

[Composer\Repository\InvalidRepositoryException]
Invalid repository data in /opt/librenms/vendor/composer/installed.json, packages could not be loaded: [Seld\JsonLint\ParsingException] “/opt/librenms/vendor/composer/installed.json” does not contain valid JSON

thanks to another post: Poller thinks it is broken after 1.64 update, but it isn't

I have found the way to fix it:

  • remove vendor folder

  • ./scripts/composer_wrapper.php install --no-dev

now validate is happy

librenms@librenms:~$ ./validate.php
