# Description

From @maxim-uvarov's
[post](https://discord.com/channels/601130461678272522/1227612017171501136/1228656319704203375).

When calling `to-lazy` back to back in a pipeline, an error should not
occur:

```
> [[a b]; [6 2] [1 4] [4 1]] | polars into-lazy | polars into-lazy
Error: nu::shell::cant_convert

  × Can't convert to NuDataFrame.
   ╭─[entry #1:1:30]
 1 │ [[a b]; [6 2] [1 4] [4 1]] | polars into-lazy | polars into-lazy
   ·                              ────────┬───────
   ·                                      ╰── can't convert NuLazyFrameCustomValue to NuDataFrame
   ╰────
 ```

This pull request ensures that custom value's of NuLazyFrameCustomValue are properly converted when passed in.
