Does someone know what can cause this?

pulumi:providers:aws aws.eu-west-1.kafka  
    pulumi:pulumi:Stack security-groups-prod running error: an unhandled error occurred: Program exited with non-zero exit code: -1
    pulumi:pulumi:Stack security-groups-prod **failed** 1 error
 
Diagnostics:
  pulumi:pulumi:Stack (security-groups-prod):
    error: an unhandled error occurred: Program exited with non-zero exit code: -1

I try multiple things. I remove my added changes and fix everything with the state to re-get that error again…

This might be out of memory error, I'm not sure what exit code we get in those cases. You could try adding some pulumi.log lines to your program to see progress its making to help find at what point it's exiting

Ok I can try to see if that’s the problem.
