Thank you for this report! I'm wondering if this is hiding another issue as we don't really use fansi in contexts different than debugging and error handling. I'll investigate.

[lbialy]

Ok, so this is a much bigger problem than just fansi having issues with parsing some escape codes. It seems Pulumi engine does something to escape codes and even if I disable trace logging that leads to this exception the besom program does not terminate at all in your sample. I guess something goes horribly wrong on pulumi's side but I'm still researching.

Ha, problem is on our side (in fansi and our pretty printer). I have a solution that works.
