the files I upload with the api arrive corrupted
Hello, my name is Bernardo, I am wanting to implement the Dropbox API to a support system. I use the example that dropbox gives on github to upload files, in my code it works but when I enter the dro...
When uploading files to Dropbox via the Dropbox API, Dropbox will save whatever data you supply, so you'll need to make sure you're sending the exact correct data you want saved. In your code, I see you're calling the filesUpload method to upload the file. When doing so, you supply the data you want to upload in the 'contents' parameter.
In your code, you're sending the contents of the 'e' variable to that 'contents' parameter. You'll need to make sure that the data you're sending there is exactly and only the data for the file you're uploading. The 'e' variable in your code comes from the .map on your 'files' variable, but the code doesn't show where/how the 'files' variable is defined. You'll need to debug and update your code accordingly to make sure you pass in just the desired file data. (For instance, based on the other 'e.filename' usage of the 'e' variable, it looks like 'e' probably doesn't contain just the file data, but rather is an object containing some properties.)

Thanks for the response, and sorry for my English but I'm using a translator.
In the end I was able to solve it yesterday, in the "saveInDropbox" function I am sending an object as a contents parameter to the filesUpload function but I had to treat it as a binary file, I added these lines to the code to the try statement
try {
const content = fs.readFileSync(e.path);
dbx
.filesUpload({ path: "/" + e.filename, contents: content })
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.error(error.error || error);
});
} catch (error) {
console.error("Error reading file:", error);
}
and it worked, Now the only thing left to solve is the issue that the token only lasts 3 hours, but I saw that there is a tutorial for that

Yes, Dropbox issues short-lived access tokens (and optional refresh tokens) instead of long-lived access tokens. Apps can still get long-term access by requesting "offline" access though, in which case the app receives a "refresh token" that can be used to retrieve new short-lived access tokens as needed, without further manual user intervention. Refresh tokens do not expire automatically and can be used repeatedly. You can find more information in the OAuth Guide and authorization documentation. There's a basic outline of processing this flow in this blog post which may serve as a useful example.
For examples of implementing this with the Dropbox JavaScript SDK, please refer to the examples included in the "examples" folder in the SDK. As long as you supply the necessary credentials, for instance, set the app key (a.k.a. client ID) and refresh token, like shown in this example for the JavaScript SDK, the SDK will actually handle refresh process for you automatically. (Note that the app secret is also required if the app does not use PKCE.) The SDK will automatically catch expired access token errors and call the API to get a new short-lived access token when needed.
