Names attribute in cols for pivot_longer results in "Can't rename variables in this context."

[JamesHWade]

After upgrading to v1.3 I noticed, pivot_longer fails when I pass a vector with names attributes to the cols argument.
Relevant issues: #1104 and #1160. Looks like #1405 is the breaking change?

I discovered this when trying to create custom tidymodels::recipes steps. Would it be best practice to use as.character(cols) for anything passed to pivot_longer? This may not be enough context, but here is what I was working on if more context might help.

Here is a reprex:

meats_small <- meats |> select(x_001, x_002, x_003, water, protein)

measures <- c("x_001", "x_002", "x_003")
measures_with_names <- measures
names(measures_with_names) <- measures

  pivot_longer(
    cols = all_of(measures),

was there any fix to this? I'm teaching a stat learning course. I have tidyr v1.2.1 and code is working fine, some new students have 1.3.0 and are getting the can't rename variables in this context error.

[DavisVaughan]

Just unname the vector you supplied to all_of() using unname()

[DavisVaughan]

I think this is a case where the error message should be improved in tidyselect r-lib/tidyselect#336
