EIP-1559 eth_call fails when using maxPriorityFeePerGas without maxFeePerGas

[mjay0]

Describe the bug
When doing eth_call with EIP-1559 transaction with maxPriorityFeePerGas and without maxFeePerGas, transaction fails.
Returned error: err: max priority fee per gas higher than max fee per gas: address 0x0000000000000000000000000000000000000123, maxPriorityFeePerGas: 50000000000, maxFeePerGas: 0 (supplied gas 1500000)
Same transaction with eth_sendtransaction works fine.

To Reproduce
eth_call smart contract function with maxPriorityFeePerGas specified and without maxFeePerGas

Expected behavior
Would expect eth_call and eth_sendtransaction to both be either fine without maxFeePerGas or both fail without maxFeePerGas

Operating System
Ubuntu 20.04 - avalanche/1.7.2

Can you supply the exact details of the two calls that you're making?
