Error "expectedAmount must be a positive integer" is confusing when creating a request

[MantisClone]

Problem

When creating a request, the expectedAmount property can be expressed as a number OR string. However, when expressed as a number, it cannot exceed 2^53 - 1 (9,007,199,254,740,991) which would result in a loss of precision. In this case, it throws the error "expectedAmount must be a positive integer".

When this error message occurs, the best solution is to express the expectedAmount as a string.

The error message doesn't make this solution clear.

Solution

• Change the error message (in all the places where it occurs) to better explain the solution.
• Update the docs to better explain this.
