I'm new to Rust and Near Protocol. During training I faced the following problem: If you follow the example log!( r#"EVENT_JSON:{"standard": "nepXXX", "version": "1.0.0", "event": "YYY", "data": {"token_id": "{}"}}"#, token_id ); of https://nomicon.io/Standards/EventsFormat, it gives an error 'Invalid format string'.

If the quotes are " replaced by ' log!( r#'EVENT_JSON:{"standard": "nepXXX", "version": "1.0.0", "event": "YYY", "data": {"token_id": "{}"}}'#, token_id );, then this error disappears, but during the build contract gives the following error: image error

How can this problem be solved?

Do not post images as text. And post the full error in both cases. – Chayim Friedman Jun 29 '22 at 14:29

`{` and `}` have special meaning in a format string. You need to double them `{{`/`}}` in order to escape that behavior – kmdreko Jun 29 '22 at 14:36
