Unexpected token ')' on api subscribtion

I have this API call in an angular application

async upload(file: FileToUpload) { // this is where the error occurs
file.id = UUID.UUID();

this.delegates.fileManager.uploadFile(file).subscribe({
next: async () => {
this.files = await (await this.delegates.fileManager.getFilesAsync()).files;
console.log(this.files);
}
});
}


the function should upload the file and refresh the file listing with an another api call. This aproach works on the delete function

async deleteFile(file: FileToUpload) {
this.delegates.fileManager.deleteFileById(file.id).subscribe({
next: async () => {
this.files = await (await this.delegates.fileManager.getFilesAsync()).files;
}
})
}


and while the uploading works, the list doesn't refresh instantly as I have to refresh the page to see the new item. It throws ERROR SyntaxError: Unexpected token ')' even if the this.files = await (await this.delegates.fileManager.getFilesAsync()).files; is not here.
