Hi, thank you for your reply. Now I have the solution.
Rootcause:
-
[ethjs-query] wile formatting outputs from RPC← This error’s hint about gas limit. - Multiple pending transactions. ← I am trying to increase gas cost but still pending because of blocked tx.
Solution : NONCE + GAS
- Customize NONCE to clear pending transaction and
- Increase gas limit by turn on 'Advanced gas controls.
*you must apply both method at the same issued transaction to solve this : )
Ref: Both
Good luck to all of you having this problem 
.
