What is your chrome(ium) version?

[dineshkumar14062001]

Version 124.0.6367.118 (Official Build) (64-bit)
it is working on my local machine but this error rising in my GCP console.

[westy92]

Is Chrome installed on your GCP instance? If so, what version?

[dineshkumar14062001]

we have used GCP serverless, and did not use any instance.

[westy92]

Html-pdf-chrome requires chrome. You'll likely need a dedicated instance running with a port exposed that your serverless functions can connect to and use.

[dineshkumar14062001]

ok, thank you. I need another question I have printed more than 2000 pages it takes more than 20 minutes, how can I shorten the print pdf?

[westy92]

If you have one instance of Chrome running, monitor its CPU/memory usage. You may need to limit the concurrency of how many simultaneous PDFs you are generating. If the 2000 pages is a single PDF, consider splitting it up into smaller jobs.
