error while running Age-Viewer using : npm run start

[hamid-irannejad]

I did

npm run setup
and then
npm run start
but I got the following errors:
internal/modules/cjs/loader.js:883
throw err;
^

Error: Cannot find module '@babel/runtime/helpers/interopRequireDefault'

  How can I solve this problem?

The below lines are also the remaining part of the error I got by running "npm run start" command.

The first part i have solved installing babel/runtime by itself throught a command
npm install @babel/runtime

But the second i still have issues with, i don't know why it happens

Thanks for your comment. I already solved my problem by searching the literature and using AI.
Your comment is true for solving the first part of the problem. Should install:

npm install @babel/runtime

and then:

cd $HOME/age-viewer/frontend/src/components/cypherresult/presentations/
Open CypherResultTable.jsx and find line 23. Replace the problematic import:
// OLD (problematic line):
import { uuid } from 'cytoscape/src/util';

// NEW (working solution):
import uuid from 'react-uuid';

and then:

cd $HOME/age-viewer/frontend
npm install react-uuid

Finally:

npm run start

This completely solves the error and opens the fully functional browser for using.

Even after this I got following error:

@mstrYoda I was able to fix the same error based on this comment on issue #166

you can fix this executing before export NODE_OPTIONS=--openssl-legacy-provider

I.e. by running with this:

NODE_OPTIONS=--openssl-legacy-provider npm run start
