plasma-calculator errors in pc._create_output_layout()

[jhlq]

Bug description

I ran plasma-calculator and the automatically opened file cannot be found but when I enter http://localhost:8866/ the page shows, however I cannot get it to calculate any outputs. The full output in the terminal is as follows:
