How to make installable extension for OpenCart4

Question

I have an custom extension that is working fine with OpenCart V2 and V3 but when I try to install that extension on V4 it is showing that there is no install.json file in it.
I created a new custom extension having only install.json in it as mentioned in one tutorial but the error remain same.
Can anyone help with it
Thank you

Answer 1

so create this install.json file instead install.xml file must contain:

{
  "name": "extension name",
  "version": "x.x.x.x",
  "author": "author name",
  "link": "https://your_site.com"
}

But this not only install.json file issue. you should to check how modules is build in Version OC4. File structure is changed.
