Quick answer: Use the exact row name (case-sensitive), make sure the lookup struct matches the table's row struct, and confirm the Data Table asset reference is set.
A Data Table lookup that finds nothing is a name or struct mismatch. Here is how to make it resolve.
How to fix it
1. Match the row name exactly
Get Data Table Row uses the row name as it appears in the table, and it is case-sensitive. A mismatched or misspelled name returns not-found. Copy the name from the table.
2. Match the row struct
The struct you read into must be the same struct the Data Table was built with. A different struct fails the lookup. Confirm both use the same row structure.
3. Check the table reference
A null Data Table reference returns nothing. Make sure the asset is assigned in the property or loaded before you query it.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every Unreal Engine error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
