Error: Unknown field countLegs on MemberAccess #8048 of type TokenId.

[ezcodeslide]

I ran into an issue using InferType.isFunctionCallExternal(). Not sure if I'm doing something wrong but wanted to reach out for an assessment/recommendation. I'm using solc-typed-ast 18.1.3.

Calling code:

// solcVersion === '0.8.25'
const inferType: InferType = new InferType(solcVersion);
// call is an instance of FunctionCall
return inferType.isFunctionCallExternal(call);

Error info:

I updated to solc-typed-ast 18.1.6. Now I get a different error.

SolTypeError: Unexpected argument type literal_hex_string to builtin function bytes.concat in FunctionCall #3519.
