How Do We Reproduce?

After updating file-loader from v4.2.0 to v5.0.2 I am getting this error.

@markusdanek no one here closed the problem, problem in this package and should be fixed here

Cannot read property 'tagName' of null #362

Look on the open label in top of the issue

[markusdanek]

@evilebottnawi Sorry I mistook the label with the other issue and saw also your comment that file-loader is using this package and that ESModule breaks it.

[gregberge]

Relative to #367, will be fixed in v5.

@gregberge after installing the latest @svgr/webpack version ("@svgr/webpack": "^5.0.1"). I still got the same problem #374

./src/assets/images/404.svg (./node_modules/@svgr/webpack/lib?-svgo,+titleProp,+ref!./src/assets/images/404.svg)
TypeError: Cannot read property 'tagName' of null

I had the same issue when I tried to rebase and got some new changes in package.json. I ran npm install again, and after downloading some packages, I no longer had this issue.

[erikmartinjordan]

I experienced this issue and detected a semicolon (;) at the end of the svg file. Deleting the semicolon solved it.
