Hi I am new to solana and i am testing my mint nft contract , while testing when i import my program using :

import { SolanaNftAnchor } from "../target/types/solana_nft_anchor";

It gives me an error: Type 'SolanaNftAnchor' does not satisfy the constraint 'Idl'. Type 'SolanaNftAnchor' is missing the following properties from type 'Idl': address, metadata enter image description here

While the json in /target/idl/solana-nft-anchor.json contains metadata and address but /target/types/solana-nft-anchor.ts doesnt.

anchor : 0.30.0

Program is successfully Deployed

As per this answer, it's because the IDL spec was rewritten with the 0.0.30 release and it's incompatible with previous versions of anchor.

Please update your anchor TS client version to 0.0.29 "@coral-xyz/anchor": "^0.29.0",

  • yes exactly i am importing same like this. and i actually follow your tutorial. Commented Apr 27 at 4:56
  • could you share the repo? Other thing to try, 1. restart the TS dev server. 2. run anchor test to regenerate the idl and types from the build step. 3. downgrade to a lower version of anchor, preferably the one specified on the tutorial
