I am trying to upload an image to ipfs using ipfs.files.add() function but it is causing me this error

Uncaught TypeError: Cannot read property 'add' of undefined

The code:

captureFile(event){
 event.preventDefault();
 const file=event.target.files[0];
 const reader=new window.FileReader();
 reader.readAsArrayBuffer(file);
 reader.onloadend = () => {
 this.setState({buffer:Buffer(reader.result)});
 console.log('buffer',this.state.buffer);
 }

}
onSubmit(event){
 event.preventDefault();
 ipfs.files.add(this.state.buffer, ( error , result ) => {

 if(error){
   console.error(error);

 }
 else{
   console.log("success");
 }
this.setState({ipfshash : result[0].hash});
console.log('ipfshash',this.state.ipfshash);
 }

 );
 }

  • You should provide the full code, ideally a repos link. But it seems a JS issue more than an Ethereum or IPFS one. At least an issue with the lib you use which should be asked on the lib's support like gitter or github issues. Feb 26, 2019 at 10:22
