I've a dockerfile as below, but during `RUN npm ci` step, there is a warning,

> 
> npm WARN old lockfile The package-lock.json file was created with an old version of npm
> 
> 
> 

which I can not able to figure out..

I tried with npm install rather npm ci and added the `--package-lock` flag, but I am still getting this warning. It’s a kind of warning that I have to ignore it or what should I do to solve this?

```none
Step 12/26 : RUN npm ci --production --package-lock &&     npm ci --production --package-lock --prefix ./ui-runner
 ---> Running in 3473c209b98c
npm WARN old lockfile
npm WARN old lockfile The package-lock.json file was created with an old version of npm,
npm WARN old lockfile so supplemental metadata must be fetched from the registry.
npm WARN old lockfile
npm WARN old lockfile This is a one-time fix-up, please be patient...
npm WARN old lockfile

```

Here is my *Dockerfile*.
