@kou or @zeroshade, any more comments here?

@paleolimbot am I right in thinking the failures are actual problems? (Also, I think you've brought up that Snowflake logging output before...we should report upstream/try to suppress it)

Hmm..that's a very strange error. It's not an actual problem in the sense that I don't think anything is not working, there must be something about the output that's being generated from the example or test that R CMD check doesn't know what to do with. I will take a look today.

Ok, the offending error message is:

time="2025-03-11T12:51:47Z" level=info msg="Credentials cache path: /home/runner/.cache/snowflake/temporary_credential.json" func="gosnowflake.(*defaultLogger).Infof" file="log.go:182"

In R you're not supposed to write to stderr directly, you're supposed to write to R's specific stderr stream (so that those messages can be captured by R things), and I am wondering if something in R CMD check is getting some mashup of the log message and what it intended to read by accident. This doesn't reproduce locally for me (maybe because I have no credentials when I run the examples, though).

This is probably unrelated to this particular change (the R checks maybe haven't run on main for a while since I haven't updated anything 😬 ). I'll open a follow-up (and maybe a short-term solution would be to set the log level to warning rather than info?).

Thanks for digging into it!

I think the log message is coming from gosnowflake, though, so maybe the easiest thing is just a PR to remove the stray log (I can do this in a bit)
