I have used abis creation in frontend folder as I have described [here](https://forum.fuel.network/t/how-to-build-predicate-ad-create-abi-for-predicate/2467/4) but after I have noticed that BN type is not provided in imports from fuel library. Seems like something wrong with typegen for predicates. ![image](https://us1.discourse-cdn.com/flex022/uploads/fuel/original/2X/6/67a23519c7331781484b9bee71cf5a9af23b0290.png) these are my version for packages ```auto Fuels version: 0.40.0 Forc version: 0.35.5 Fuel-Core version: 0.17.3 ``` ---

looking forward for solving this problem, but also I have found another one, please have a look maybe they are related > [@Cant create predicate instance following Use type tutorial in ts sdk](https://forum.fuel.network/t/cant-create-predicate-instance-following-use-type-tutorial-in-ts-sdk/2490): > > Hey devs! I have tried to create instance of predicate with following code, but it failed, please have a look) Link to tutorial that used - [Using Generated Types | Fuels-ts](https://fuellabs.github.io/fuels-ts/guide/abi-typegen/using-generated-types.html#using-generated-predicate-types) Link to my repo with code - [GitHub - compolabs/test-predicate-ts](https://github.com/compolabs/test-predicate-ts) ---
