IDL Incompatibility and Playground-to-Local Contract Errors

[NIXBLACK11]

I am encountering issues with the playground. Specifically:

1. The idl.json file generated by the playground is incompatible with the frontend and does not include types.
   This is the demo I am following Intro to Solana client-side Anchor development.
2. I cannot deploy the smart contract locally due to errors when running the same program on my machine that works fine in the playground environment.

1. The idl.json file generated by the playground is incompatible with the frontend and does not include types.
   This is the demo I am following Intro to Solana client-side Anchor development.

The reason for this is that Playground is currently using an older Anchor version (v0.29), and a new IDL standard has been introduced in Anchor v0.30 (coral-xyz/anchor#2824).

However, you can still use the IDL exported from Playground by converting it to the new standard. You can also generate TypeScript defininiton for the IDL by using the new anchor idl type command. Note that both of these are only available in anchor CLI v0.30.1 currently, so you'd need to have it installed locally. The Anchor TS package (@coral-xyz/anchor) also needs to be on version v0.30.1 for compatibility.

2. I cannot deploy the smart contract locally due to errors when running the same program on my machine that works fine in the playground environment.

There could be many reasons for this, so it would help if you provided more details about the errors.

Thanks, this helped me convert it to the new standard.
The second issue was program-specific, and I’ve resolved it.
Thank you for the help.
