Unable to setup export server in node application with npm package highcharts-export-server v3.0.3 and above

[satyam20satyam]

We are using npm package highcharts-export-server in our express based server.
Axis label is not getting translated as per selected lang, this is same as #434 which is fixed and released in 3.0.3 version but while we are using version 3.0.3 or above, we are getting error while starting the server. We drilled more into the code and found it is happening because coreScript is undefined.
TypeError: Cannot read properties of undefined (reading 'map').

After that server got started with this above error and we tried to export the chart and got another error

Tue Mar 19 2024 23:06:31 GMT+0530 [verbose] - [chart] Starting exporting process.
Tue Mar 19 2024 23:06:31 GMT+0530 [verbose] - [chart] Attempting to export from a raw input.
TypeError: Cannot read properties of undefined (reading 'allowCodeExecution')

This is the request body we are passing and below are the configurations.

NODE_TLS_REJECT_UNAUTHORIZED=0
ACCEPT_HIGHCHARTS_LICENSE=1
HIGHCHARTS_ALLOW_CODE_EXECUTION=1
HIGHCHARTS_ALLOW_FILE_RESOURCES=1
HIGHCHARTS_LOG_LEVEL=2

await exporter.initPool({
    maxWorkers: 5,
    initialWorkers: 5,
    workLimit: 50,
    customCode: { allowCodeExecution: true, allowFileResources: true },
  });

The same configuration is working fine in npm highcharts-export-server v3.0.1 with translation issue.

Can someone please help me here to unblock me.
