Encountered by: validatorsdevelopers

From Chain Metadata
Preimage has already been noted on-chain.
What This Means
A preimage with this hash has already been stored. Preimages are identified by the Blake2 hash of their content, so identical call data will always produce the same hash.
Common Causes
- Submitting the same preimage (call data) that was already stored
- Another account already noted this exact preimage
- Accidentally calling note_preimage twice
How to Fix
- Query Preimage.StatusFor with the hash to confirm it exists
- Use the existing preimage — no need to store it again
- If you need a different preimage, modify the call parameters
