Description

Example tx: 2LQT3oZSoAyrzAC59wfMfbiZtF74YPcw5rQuaAmBu1FhuVe1f3CZoms8wKETJYVx8q9Bi8wT8v337iMDg4PJysF2

The problem is caused by exact span check here

Proposed solution: check if length of the data is equal to 35 (data with empty freeze authority) or 67 (freeze authority exists) bytes

Contributor guide

Research direction
Inspect the failing transaction and trace the decodeInitializeMintInstruction function to verify the exact span check. Check if the data length should be 35 (no freeze authority) or 67 (freeze authority exists) and update the condition accordingly.
