I have run npm i @types/node, and also some of the other fixes I've found online (such as ensuring tsconfig has "types": ["node"] and "typeRoots": [ "node_modules/@types" ] in it). Nothing is resolving this issue.
This project was started from the angular 5 version of this repo, and this is the last step of updating it to the angular 7 version.
If it matters:
npm -v : 5.6.0
node -v: 8.9.4

Example usage causing the first error:

Another error (buffer)
public downloadFile(): void {

this.downloadInProgress = true;
let fileNamePrefix = this.dataEndpoint["displayName"].replace("/", "-");
this.system.getDataManagementFile(this.dataEndpoint["domain"], this.dataEndpoint["fileEndpoint"]).then(

const data: Blob = new Blob([byteArray], {

});

this.downloadInProgress = false;
}, err => {
console.log("Unable to download file");
this.downloadInProgress = false;
this.message = "Failed to download file";
});

Same issue for me... Any update @dresdor
dresdor commentedon Jul 3, 2019
@RobertThwaite No, unfortunately. I elected to update to angular 6 instead, as that was doable without errors (we were on 5). My current guess is that there's a dependency on a higher version of node or npm (or both) but updating would be a breaking change for our development team, so we need to get some fixes in place before we can attempt it.
RobertThwaite commentedon Jul 3, 2019
@dresdor DAMN! exact same boat as you. Was hoping you was the cure! Thanks for initial outlook, I'll give another couple hours then come to same conclusion as you then.
