: Your post should have at least one character or one image.

Error message

${validation.name}: Your post should have at least one character or one image.

What it means

Per-provider validation (Zod schemas in libs/.../validation) checks that each post variant has content or media. emptyContent=true means the target channel received a post with no text and no image, which the provider rejects.

Solutions

1. Add at least one character of content or attach an image to every channel variant
2. Remove the empty per-channel variant from the posts array instead of submitting it blank
3. Check that image URLs survived upload; re-upload if the media failed
4. Validate client-side per provider: content.trim() || image.length

Example fix

// before
{ integration: { id }, content: '', image: [] }
// after
{ integration: { id }, content: 'Check this out!', image: [] }
// or
{ integration: { id }, content: '', image: [uploadedImageUrl] }

const hasContent = body.posts.every((p) => (p.content ?? '').trim().length > 0 || (p.image ?? []).length > 0);
if (hasContent) await createPost(orgId, body);

When it happens

Trigger: Creating/updating a post where a per-channel variant has empty content and an empty/undefined image array (e.g. clearing the text box for one channel while drafting).

Common situations: Multi-channel composer with an emptied per-channel override; image upload failing silently leaving posts with neither text nor media; API payloads with content: '' and image: [].

Understand the failure class
