ethereum/solidity#14142 (comment)

this error is due to a bug on that release and the proper support for constantinoble EVM version through the command line was only added in version 0.4.22. See: ethereum/solidity@a59d6d2 and ethereum/solidity#3713

nice find!
please add a short explanation to the docs why we use 0.4.22 but link to the 0.4.21 release:

we have a failing test, could you please check if we need another 0.4.21 constant for this?

proper support for constantinoble EVM version through the command line was only added in version 0.4.22

I'm not sure if this affects the standard-json input

ethers-rs/ethers-solc/src/artifacts/mod.rs

Lines 758 to 760 in 6ebb1b2

	// the EVM version flag was only added at 0.4.21
	// we work our way backwards
	if version >= &CONSTANTINOPLE_SOLC {
