Memory Leak with axios-module from Nuxt - memory-leaks

Question

I have a memory leak using #nuxtjs/axios. I don't really know if it's my code or the plugin.
My project requires 2 axios instances to run.
One to get an "anonymous token" to be allowed to access the API.
And a second one to use that token and make my API calls.
const createDefaultClient = (agent, $axios, $appInsights, inject) => {
const defaultClient = $axios.create({
withCredentials: true,
httpsAgent: agent
})
defaultClient.setBaseURL(
process.server ? 'http://localhost:3000' : window.location.origin
)
defaultClient.onResponseError(error => {
logError(error, $appInsights)
return Promise.reject(error)
})
inject('defaultClient', defaultClient)
return defaultClient
}
const createApiClient = (
agent,
$axios,
$cookies,
$appInsights,
defaultClient,
inject,
request
) => {
const apiClient = $axios.create({
withCredentials: true,
httpsAgent: agent
})
apiClient.setBaseURL(process.env.NUXT_ENV_BASE_API)
apiClient.onRequest(config => {
const cookieToken = $cookies.get(accessTokenCookieName)
if (cookieToken) {
config.headers.common.Authorization = `Bearer ${cookieToken}`
}
debug(`${config.__isRetryRequest ? 'Retry' : 'Request'}: ${config.url}`)
})
apiClient.onResponseError(async error => {
const originalRequest = error.config
debug(`Error ${get(error, 'response.status')}: ${error.config.url}`)
// if we get error 401 (token expiration) we will refresh the token and retry to access API
if (error.config && error.response && error.response.status === 401) {
originalRequest.__isRetryRequest = true
const refreshToken = $cookies.get(refreshTokenCookieName)
let fetchAnonymousToken = true
let response = null
// if we had a cookie try to refresh it
if (refreshToken) {
response = await defaultClient.$post(`/forms/refresh`, {
refreshToken
})
if (!response) throw new Error('Auth failure')
if (process.client) {
createAuthCookies($cookies, response, request)
}
fetchAnonymousToken = false
}
// else fetch an anonymous cookie
if (fetchAnonymousToken) {
response = await defaultClient.$get(`/forms/anonymous`)
if (!response) throw new Error('Auth failure')
if (process.client) {
createAuthCookies($cookies, response, request)
}
}
// resend API request with the new valid token
originalRequest.headers.Authorization = `Bearer ${get(
response,
'access_token'
)}`
return apiClient(originalRequest)
} else {
logError(error, $appInsights)
return Promise.reject(error)
}
})
inject('apiClient', apiClient)
}
export default function({ $axios, app, req }, inject) {
const { $cookies} = app
const agent = new https.Agent({
rejectUnauthorized: process.env.NODE_ENV !== 'development'
})
const defaultClient = createDefaultClient(agent, $axios, inject)
createApiClient(
agent,
$axios,
$cookies,
defaultClient,
inject,
req
)
}
Basically I've followed the doc here : https://axios.nuxtjs.org/extend
I've commented everything in my projet and without the API calls the memory get garbage collected.
Here the memory before the charge
Here after the charge
After a siege, we can clearly see that the memory won't go down :/
Please help me i'm desesperate..
