Hey there, @mahiraltinkaya 
Thanks for reaching out! We think it is ok to use this solution.
In terms of root cause, we think the original issue may actually be happening because your code is leaking memory, which is using up the 512 mg of memory that node.js provides. If you want to spend time debugging this further, I would suggest investigating what is causing so much memory to be used (for example, image processing, etc.) But if you are happy with the workaround, you can proceed using it!
We have this resource that you can use to get started, which includes examples with nuxt builds :
