Sometimes you face issues while running the Magento 2 command, and the solution to this issue is you just need to eliminate the memory limit while running Magento command.

So instead of running command like

php bin/magento your_command

do it like this

php -d memory_limit=-1 bin/magento your_command

Happy coding
