When I try to manipulate a DataFrame in Julia, blue wavy lines often appear, such as the following

![warning1](https://global.discourse-cdn.com/julialang/original/3X/a/f/afb5ff8c2d795413b75c57d6f2c010a62712a625.png)

and

![warning2](https://global.discourse-cdn.com/julialang/original/3X/f/e/fe3c5151c7f3d1dbd4881c2b804b67b13c73c5e5.png)

The code works fine except for the odd warning from the editor. My version of Julia is 1.8.5, and package status is

```julia
  [a93c6f00] DataFrames v1.5.0
  [1313f7d8] DataFramesMeta v0.13.0
  [f7bf1975] Impute v0.6.10
  [194296ae] LibPQ v1.15.1
  [39abe10b] MySQL v1.4.3
  [92933f4c] ProgressMeter v1.7.2
  [b0e4dd01] RollingFunctions v0.7.0
  [37e2e46d] LinearAlgebra

```

I think this is due to Julia’s own ecology rather than package conflicts, because in an environment where only `DataFrames.jl` is installed, the warning persists.

I’d like to know how to avoid this warning, or if I’ve made some easy to overlook syntax mistakes. thanks in advance!

vscode produces a lot of wrong warnings. Currently there are 49 open linter related bugs: [Issues · julia-vscode/julia-vscode · GitHub](https://github.com/julia-vscode/julia-vscode/labels/area-ls-linter)

Just try to turn these kind of warnings off or ignore them.

Thank you very much! And I finally find that add `"julia.lint.call": false` to setting.json can disable the warning message. I hope vscode (or maybe be due to Julia) could fix it soon~
