Summary

The Typescript types fail in the following case below.

Error: Type '[string, string, string, string]' is not assignable to type 'string | number'

Other information (e.g. detailed explanation, stack traces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)

The following test should pass and be able to be run without any Typescript errors:

describe('for CompactBytesArray of tuples `(...,...)[CompactBytesArray]`', () => {
      it(`encodes/decodes: [ ["0x00000002", "0xcafecafecafecafecafecafecafecafecafecafe", "0x11223344", "0xbb11bb11"] ] as (bytes4,address,bytes4,bytes4)[CompactBytesArray]`, () => {
        const schema = {
          name: 'AddressPermissions:AllowedCalls:<address>',
          key: '0x4b80742de2bf393a64c70000<address>',
          keyType: 'MappingWithGrouping',
          valueType: '(bytes4,address,bytes4,bytes4)[CompactBytesArray]',
          valueContent: '(BitArray,Address,Bytes4,Bytes4)',
        };

        const expectedEncodedValue =
          '0x002000000002cafecafecafecafecafecafecafecafecafecafe11223344bb11bb11';

        const result = ERC725.encodeData(
          [
            {
              keyName: 'AddressPermissions:AllowedCalls:<address>',
              dynamicKeyParts: address,
              value: [
                [
                  '0x00000002',
                  '0xcafecafecafecafecafecafecafecafecafecafe',
                  '0x11223344',
                  '0xbb11bb11',
                ],
              ],
            },
          ],
          [schema],
        );

        assert.equal(result.values[0], expectedEncodedValue);
      });
    });
  });
