Server not generating images: [notice] the client closed the connection before the chart was done processing

[chrcar01]

Expected behaviour

Running export server(latest in master) locally with Node 16, sending request to http://localhost:7801 should generate chart.

Actual behaviour

Client(Postman, .NET HttpClient, and curl) hangs while the server displays:

Reproduction steps

curl -H "Content-Type: application/json" -X POST -d '{"scale":8,"type":"png","infile":{"chart":{"type":"bar"},"title":{"text":"Bar Chart Sample"},"xAxis":{"categories":["Cat1","Cat2"]},"yAxis":{"min":0,"labels":{"overflow":"justify"}},"series":[{"name":"Cat1","data":[107,31]},{"name":"Cat2","data":[133,156]}]}}' http://localhost:7801 -o barchart.png

Notes

Switching to Node 14, it works as expected.
Node 15.14.0 also works, 16.0.0 seems to have introduced this behavior in Highcharts.

For me the currently working configuration is node 14 with highcharts 9.2.2.
Im running the node export server in a docker container based on node:14-bullseye-slim from docker hub.

I'm having the same problem with node:16.13.2-buster, which I tried to upgrade from node:14.17.5-buster due to some vulnerabilities and to keep Node in a LTS version

Can you share your docker config?

This PR seems to solve it: #337
Duplicate issue here: #312

As I've written there:

This should no longer be a problem in the latest Puppeteer-based version of the Export Server which I encourage you to try out.

Here's a short setup guide: https://github.com/highcharts/node-export-server#puppeteer-version-information

Please feel free to report any problems you encounter with the newest version and we will investigate it. If we notice any incompatibilities (or you report them by creating an issue) we will update our docs to include all the necessary information.

I just did npm i highcharts-export-server@3.0.0-beta.1 -g and the errors Im getting are totally inexplicable. 🤯
Upon starting server I get
