Quasar / Capacitor / Cordova error: “…/node_modules/http-proxy-middleware/dist/index has no exported member 'Config'”

[omgwalt]

I asked this at stackoverflow.com, but I thought I should ask it here, too, in case someone here knows the answer.

When I build my app with:

quasar build -m capacitor -T ios
I now get the following errors:

/Users/myusername/Documents/my-app-name/node_modules/@types/webpack-dev-server/index.d.ts ERROR in /Users/myusername/Documents/my-app-name/node_modules/@types/webpack-dev-server/index.d.ts(30,53):

TS2694: Namespace ‘"/Users/myusername/Documents/my-app-name/node_modules/http-proxy-middleware/dist/index"’ has no exported member ‘Config’.

/Users/myusername/Documents/my-app-name/node_modules/@types/webpack-dev-server/index.d.ts ERROR in /Users/myusername/Documents/my-app-name/node_modules/@types/webpack-dev-server/index.d.ts(36,29):

TS2694: Namespace ‘"/Users/myusername/Documents/my-app-name/node_modules/http-proxy-middleware/dist/index"’ has no exported member ‘Config’.

I get the same result if I build with Cordova:
quasar build -m cordova -T ios

Any references to this kind of error that I can find online describe situations that do not seem to be related to my own.

The last time I built my app (about a 3-4 weeks ago), it built just fine.

I have tried deleting all of the following and rebuilding:

node_modules
src_capacitor
package-lock.json
yarn.lock

You have two options, reinstall the project or add into package.json => dependencies “http-proxy-middleware@0.19.x” version. In default version used by “@quasar/cli” is “http-proxy-middleware@1.x.x”, I added v 0.19 and it works for me without errors in the console.
