The code is pretty simple, see below [image: Screen Shot 2021-12-08 at 1.23.19 PM.png] I added breakpoints at line 18. I manually removed the file /tmp/db, and then continued to run the file. Everything was working well. Is this a bug or expected behavior? -- You received this message becaus

Clearly that's a workaround though. Like how you can copy a slice of bytes without calling copy by casting it to a string and then back to []bytes. It gets the job done, but it's weird and not obvious. On Wednesday, July 15, 2020 at 12:14:19 PM UTC-7, Axel Wagner wrote: > > Why not just accept
