Error Promises must be awaited, end with a call to .catch, end with a call to .then with a rejection handler or be explicitly marked as ignored with the `void` operator @typescript-eslint/no-floating-promises

Tried this, it updates the title as meta data but attachment is not loading into the list
Sandeep Pradhan6y ago
Could you please tell me about the getFolderByServerRelativeUrl syntax and what do you mean by Title is metadata, is it the title in your list?

Yeoman generator will perform a scaffolding process to generate the solution. The scaffolding process will take a significant amount of time.

Once the scaffolding process is completed, lock down the version of project dependencies by running the below command:

npm shrinkwrap

In the command prompt, type below command to open the solution in the code editor of your choice.

code .

NPM Packages Used,

On the command prompt, run below command.

npm i @pnp/logging @pnp/common @pnp/odata @pnp/sp --save

for Pollyfills

npm install --save @pnp/polyfill-ie11

in PnpFileUpload.tsx

import "@pnp/polyfill-ie11";
import {sp} from '@pnp/sp';
export default class PnpFileUpload extends React.Component<IPnpFileUploadProps, {}> {
constructor(props) {
super(props);
this.filesave = this.filesave.bind(this);
}
public render(): React.ReactElement<IPnpFileUploadProps> {
return (
<div>
<div>
<input type="file" name="myFile" id="newfile"></input></div>
<div>
<button onClick={this.filesave}>
UploadFile
</button></div>
</div>
);
}
private filesave(){
let myfile = (document.querySelector("#newfile") as HTMLInputElement).files[0];
if (myfile.size <= 10485760) {
sp.web.getFolderByServerRelativeUrl("/sites/SPCapabilityTeam/MadhanNC/PnpLibrary").files.add(myfile.name, myfile, true).then(f => {
console.log("File Uploaded");
f.file.getItem().then(item => {
item.update({
Title: "Metadata Updated"
}).then((myupdate) => {
console.log(myupdate);
console.log("Metadata Updated");
});
});
});
}
else{
sp.web.getFolderByServerRelativeUrl("/sites/SPCapabilityTeam/MadhanNC/PnpLibrary")
.files.addChunked(myfile.name, myfile)
.then(({ file }) => file.getItem()).then((item:any) => {
console.log("File Uploaded");
return item.update({
Title: 'Metadata Updated'
}).then((myupdate) => {
console.log(myupdate);
console.log("Metadata Updated");
});
}).catch(console.log);
}}}

Here, my list name is PnpLibrary and Title is metadata.

If we upload below 10mb, 1st method will hit. If above 10 mb, 2nd Method will hit.

Happy Coding :)
