I've added pallet-nft and pallet-uniques in Relay Chain. All the things are working fine but when I'm signing the transaction in the pallet-uniques fn create(collection,admin), it is showing me this error:

1002: Verification Error: Runtime error: Execution failed: Execution aborted due to trap: wasm trap: wasm unreachable instruction executed WASM backtrace: 0: 0x547257 - !rust_begin_unwind 1: 0x54ee - !core::panicking::panic_fmt::hca80ede79c2b9c5b 2: 0x29ff1c - !TaggedTransactionQueue_validate_transaction : RuntimeApi, Execution failed: Execution aborted due to trap: wasm trap: wasm unreachable instruction executed\nWASM backtrace:\n\n 0: 0x547257 - !rust_begin_unwind\n 1: 0x54ee

  • Could you paste the entire error message in as text too, it will be useful for searches in the future.

  • Try refreshing polkadot-js. Do you have added the pallets through a runtime upgrade?

You probably need to specify custom types.json in polkadot.js.org. These links might be helpful:
