Allow for posting without a file

[davidgs]

This should allow you to post without a file uploaded

Thank you for the PR! You will also need to modify https://github.com/run-llama/crossposter/blob/main/frontend/src/app/api/post/route.ts to only upload media attachments if they are present; at the moment posting fails with a 500 on all 3 services.

Can you send me the console output when you try to post without media?

I would expect that

 const platform = formData.get('platform') as string;

    console.log("Attached Media", media)

would print null if there's no media.

That's true! Unfortunately one needs to handle this in several other places:

1. Here: https://github.com/run-llama/crossposter/blob/main/frontend/src/app/api/post/route.ts#L60-L75

You need to check if there's media and neither upload it nor attempt to create a tweet with media IDs attached.

2. Here: https://github.com/run-llama/crossposter/blob/main/frontend/src/app/api/post/route.ts#L98-L103

This is the most troublesome; the library for LinkedIn doesn't have a post-without-media option! You need to add one.

3. Here: https://github.com/run-llama/crossposter/blob/main/frontend/src/app/api/post/route.ts#L123-L131

You likewise need to modify the bluesky poster to have an option to post without attached media.
