Invalid types provided. Map is <Int, Int>, but type String? was provided to variable. Moreover, the page does not mention String is a valid map value type.

Also, in on the same page:

arr: map<Int, Int>; // "array" of String values as a map

@anton-trunov hey, you have just edited my description and added Moreover, the page does not mention String is a valid map value type.. Seem like tact does not support String as map type yet. Or i am mistaken?

@a-bahdanau Right, String is not supported, although the typechecker does not always report it: https://github.com/tact-lang/tact/issues/701
