ipfs.add is not working

I am trying to upload my file to IPFS and save its hash to my Ethereum contract but neither ipfs.add nor ipfs.files.add is working for me…
I have tried usin for loop i.e.

for await (const result of ipfs.add(this.state.buffer)) {
      console.log(result);
  }

and also this way:

ipfs.add(this.state.buffer, (error, ipfsHash) => 
    {
      console.log('Trying to add');
      if(error) {
        console.error(error)
        return
      }
    })

but both of them are not working…. I’ve tried to debug my code but the control doesn’t go beyond ipfs.add line….
Any help will be highly recommended as I am not able to find any help on the internet and stuck here badly from past few hours..
