Video cannot be loaded

Error message

Video cannot be loaded

What it means

Thrown while preparing the admin product-video grid (PrepareProductVideoListModel). For each ProductVideo mapping row the factory loads the Video via _videoService.GetVideoByIdAsync(productVideo.VideoId); if null, it throws a bare System.Exception that propagates. It indicates the ProductVideoMapping join references a VideoId with no corresponding Video record. Same structural defect as the picture variant: an orphaned mapping row.

Solutions

1. Remove or repair the orphaned ProductVideoMapping rows whose VideoId lacks a Video record.
2. Re-upload the missing video and re-attach it to the product.
3. Integrity check: SELECT * FROM Product_Video_Mapping pvm LEFT JOIN Video v ON v.Id = pvm.VideoId WHERE v.Id IS NULL; delete those rows.
4. Restore the Video table from backup if several are missing.

Example fix

// before
var video = (await _videoService.GetVideoByIdAsync(productVideo.VideoId))
    ?? throw new Exception("Video cannot be loaded");
// after (skip broken row)
var video = await _videoService.GetVideoByIdAsync(productVideo.VideoId);
if (video is null)
{
    await _logger.WarningAsync($"ProductVideo mapping {productVideo.Id} references missing video {productVideo.VideoId}");
    return null;
}

// Confirm each video mapping resolves before building the grid.
var productVideos = await _productService.GetProductVideosByProductIdAsync(product.Id);
var orphans = productVideos.Where(pv => (await _videoService.GetVideoByIdAsync(pv.VideoId)) is null).ToList();
if (orphans.Any())
    await _logger.WarningAsync($"{orphans.Count} product-video mappings reference missing videos.");

static bool VideoResolved(Video v) => v is not null;

try { /* PrepareToGridAsync body */ }
catch (Exception ex) when (ex.Message == "Video cannot be loaded")
{
    await _logger.WarningAsync(ex.Message, ex);
    /* return empty/partial grid */
}

When it happens

Trigger: A ProductVideoMapping row has a VideoId for which VideoService.GetVideoByIdAsync returns null. Caused by a video record deleted while its product mapping remained, or a failed video ingestion that left a dangling mapping.

Common situations: Video record hard-deleted from DB without removing ProductVideoMapping; failed upload leaving orphan mapping; storage/backend migration dropping video entries; video plugin uninstall removing Video rows but not mappings.
