Describe the Problem

ethers Interface throws error. I've tried all v6.x.x and all the same but it worked with v5.7.0. so I guess something is changed between them. ofc I used ethers.utils.Interface with v5.7.0.

Code Snippet

const iface = new ethers.Interface([
    'function receive(bytes)',
])
const functionFragment = iface.getFunction('receive')

The name receive is reserved. Can you try just "receive(bytes)" (drop the word “function”)?

[ricmoo]

The error were improved in v6.11.0. The issue was using a function with a reserved name, and can be resolved by dropping the function specifier (as it is a receive fallback). Let me know if you still have any issues.

Thanks! :)
