Session start error (500)

Hi,
I’m looking for an assistance

I have a react application and I want to have two different tawk widgets:
one widget for public pages available for guest
another widget for dashboard pages for our logged-in clients

I added TawkMessengerReact component with switchWidget and setAttributes functions

import { useEffect, useRef } from "react"
import TawkMessengerReact from "@tawk.to/tawk-messenger-react"

...

const TawkComponent = () => {
  ...
  
  const handleSwitchWidget = () => {
    if (window.Tawk_API && typeof window.Tawk_API.switchWidget === "function") {
      window.Tawk_API.switchWidget(
        { propertyId, widgetId },
        (error: string) => {
          if (error) {
            console.log("--- error ---")
            console.log(error)
            return
          }
        },
      )
    }
  }

  const handleSetAttributes = () => {
    if (
      window.Tawk_API &&
      typeof window.Tawk_API.setAttributes === "function"
    ) {
      window.Tawk_API.setAttributes(
        {
          name,
          email,
          hash: signature,
        },
        (error: string) => {
          if (error) {
            console.log("--- error ---")
            console.log(error)

            return
          }
        },
      )
    }
  }

  useEffect(() => {
    if (TAWK_DISABLED) {
      return
    }

    handleFetchTawk()
  }, [clientId])

  useEffect(() => {
    if (TAWK_DISABLED) {
      return
    }

    handleSwitchWidget()

    if (isLoggedIn && isFetched) {
      handleSetAttributes()
    }
  }, [widgetId])

  return (
    <TawkMessengerReact
      useRef={tawkMessengerRef}
      propertyId={propertyId}
      widgetId={widgetId}
    />
  )
}

propertyId is the same for widgets
widgetId is defined in tawk dashboard
name, email and signature are provided by the backend
– Secure Mode was enabled in the tawk dashboard

There is some session start issue

POST https://va.tawk.to/v1/session/start

{
    ok: false,
    error: { code: "InternalServerError", message: "" },
}

after a while session and a few page refreshes session can be started successfully

POST https://va.tawk.to/v1/session/start

{
    ok: true,
    data:  ...
}

After login and widget switch I got the same session start error

POST https://va.tawk.to/v1/session/start

{
    ok: false,
    error: { code: "InternalServerError", message: "" },
}

I guess the problem is somewhere in tawk chat authentication because cleanup cookies like twk_uuid_... and twk_idm_key help to start a session

What is the proper way to switch widgets and update client attributes like name and email?

Appreciate any feedback and suggestions
