Parallel use error with exported variables

[auriou]

I want to run load tests using httpyac's parallel mode, but it doesn't work when I use javascript blocks with exported variables.
Here is an example of code that works without parallel mode, but gives errors with this mode.

{{
    const { faker } = require('@faker-js/faker');
    exports.sexType = faker.person.sexType()
    exports.password = faker.internet.password({ length: 10})
    exports.firstName = faker.person.firstName(exports.sexType)
    exports.lastName = faker.person.lastName(exports.sexType)
    exports.email = faker.internet.email({ firstName: exports.firstName, lastName: exports.lastName });
    exports.phone = faker.helpers.fromRegExp(/0[67][0-9]{8}/)
    exports.auth = "Basic " + Buffer.from(exports.firstName + ":" + exports.password).toString("base64")
}}

GET https://httpbin.org/basic-auth/{{firstName}}/{{password}}
Authorization: {{auth}}

{{
    exports.user = response.parsedBody.user;
    console.log('user', exports.user)
}}

GET https://httpbin.org/uuid
Token: {{user}}
{{
    exports.uuid = response.parsedBody.uuid;
}}

POST https://httpbin.org/anything/{{user}}
Token: {{uuid}}

It's ok without parallel

httpyac.js send senario-httpbin.http  --all  -o short 

GET https://httpbin.org/basic-auth/Carrie/KjnXrfgHzK
=> 200 (657 ms, 231 B)
