error C2338: each element in the iterator range must have the size of 1 byte，
The compilation triggered an assertion that I don't know what to do and what should I do？
thank you

[nlohmann]

Can you provide the code that triggers that error?

[daodol]

[nlohmann]

No I meant your code.

You try to parse an int vector. That does not work - just assign: j = v;.

You can use a vector of chars to parse from. This is the error message: if you parse from a vector, its elements must be 1 byte.
