Assertion failed: Cannot call unknown function compileJSON

I'm trying to verify bytecode of a contract with solc version 0.5.7 but getting the following error.

You've chosen: mainnet
? Enter compiler version. (e.g. v0.4.10+commit.f0d539ae). v0.5.7+commit.6da8b019

Contract File Link
EtherScan Link for above contract
You can see that deployed version of contract is an exact match of the Contract file from NexusMutual/smart-contracts repository but still the verifier fails to verify

As a quick attempt, @Mayur1496 can you try to run the example contracts in this repo with the original solc version and also v0.5.7 to see whether it's the same error?

If this error is only with v0.5.7, maybe can try to upgrade the solc dependency in this project and see how it goes.
