How to: ERC-1155 ID Substitution for Token URI

[Rock_Show]

I have a similar question around ID substitution.

The standard implies that the {id} MUST be replaced in all attributes within the metadata JSON. In practice I am not seeing this. Does anyone have any experience with this?

ERC1155 Metadata: OpenSea not replacing {id} with actual token ID?

I'm wondering if there are cases when OpenSea (or any client) does not replace {id} in Metadata JSON files. If the string {id} exists in any JSON value, it MUST be replaced with the actual token ID, by all client software that follows this standard. I have a case where OpenSea is simply rendering {id} as plain text for the following file: { "name": "Token id {id}", "description": "This is #{id} ", "image": "https:\/\/url.com/img?id={id}" }
