This might mean you’re missing a browserslist config.

Solution

Add browserslist field to package.json:

{
  "browserslist": [
    "last 1 chrome version",
    "last 1 firefox version",
    "last 1 safari version"
  ]
}

Or add it to .browserslistrc:

touch .browserslistrc

last 1 chrome version
last 1 firefox version
last 1 safari version
