IBC transfer is accepted, while dry-run is rejected

[Rigorously]

Executing an IBC transfer in client v0.31.6 with the --dry-run or --dry-run-wrapper flags results in a rejection:

namadac ibc-transfer --source myaddress --receiver stars1someaddress--token naan --amount 1 --channel-id channel-275 --dry-run

Dry-run result: Transaction was rejected by VPs: [
  "tnam1qcqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqvtr7x4"
].
Changed key: [

The same transaction without --dry-run is accepted:

namadac ibc-transfer --source myaddress --receiver stars1someaddress--token naan --amount 1 --channel-id channel-275

Transaction added to mempool.

Inner transaction hash: F9979352E76AAD5B2301D6807428AADA9C7170FDE5C2F3441D5C2DA0EDB3D976
Wrapper transaction accepted at height 75053. Used 27 gas.

Thank you for reporting it. Yeah, I could reproduce it.
The TempWlState which is used in dry_run_tx() doesn't have the block header because it is set in finalize_block().
IBC transfer tx tried to read the header's time to check the packet timeout and failed.
