ethers 5.0.9 breaking change

See original GitHub issue

Something changed in ethers@5.0.9 that broke the code generated by @typechain/ethers-v5 The error message below was edit to remove references to my code, replacing the contract name with <ContractName> and method signature with <methodSignature>.

Interface '<ContractName>Interface' incorrectly extends interface 'Interface'.
  Types of property 'functions' are incompatible.
    Type '{ "<methodSignature>": FunctionFragment; }' is not assignable to type '{ [name: string]: FunctionFragment; }'.
      Property '"<methodSignature>"' is incompatible with index signature.
        Type 'import("./node_modules/@ethersproject/abi/lib/fragments").FunctionFragment' is not assignable to type 'import("./node_modules/ethers/node_modules/@ethersproject/abi/lib/fragments").FunctionFragment'.
          Types of property 'gas' are incompatible.
            Type 'import("./node_modules/@ethersproject/bignumber/lib/bignumber").BigNumber | undefined' is not assignable to type 'import("./node_modules/ethers/node_modules/@ethersproject/bignumber/lib/bignumber").BigNumber | undefined'.
              Property 'toJSON' is missing in type 'import("./node_modules/@ethersproject/bignumber/lib/bignumber").BigNumber' but required in type 'import("./node_modules/ethers/node_modules/@ethersproject/bignumber/lib/bignumber").BigNumber'.ts(2430)
bignumber.d.ts(33, 5): 'toJSON' is declared here.

It is probably related to this change: https://github.com/ethers-io/ethers.js/commit/8facc1a5305b1f699aa3afc5a0a692abe7927652

The later version of ethers has had all versions locked, so depending on ^5.0.13 should solve this problem.

Sorry for the inconvenience.

Oh! Sorry, I lost track of this issue and was trying to find it.

The new build system for ethers now locks the umbrella package versions for all dependencies. So if you depend on the ethers package directly, this should never happen again. 😃
