What's Happening

When resolving a stringified number as a parameter, the template engine converts the stringified number into an actual number type. For example, given the context object

{
"signups": "100"
}

and parameter map

{
"attendees": "{{context.signups}}"
}

The returned resolved parameter object is a number type..

{
"attendees": 100
}

instead of a string

{
"attendees": "100"
}

What's expected

The expectation is that resolving a stringified number will return a the original strigified number without casting it to a number type (i.e integer or float)

How to recreate

from socless.paramresolver import ParameterResolver

context = {"signups": "100"}
resolver = ParameterResolver(context)
params = {"attendees": "{{context.signups}}"}
expected = {"attendees": "100"}

# This should throw an assertion error
assert resolver.resolve_parameters(params) == expected, "Parameter Resolver not returning expected object"

Additional notes

Adding single quotes around the template string prevents the stringified number from being cast to a number type. As an example, the below yields the correct response (note the additional single-quotes)

{
"attendees": "'{{context.signups}}'"
}
