Long query string arrays converted to objects (express issue)

[christo911]

When using get request with filter including an array of more than strings, the filter is converted from an array to an object.
This is related to express qs, as described exactly here:

https://github.com/expressjs/body-parser/issues/289

It also seems this was an issue in the past with loopback 3, and was resolved by increasing the querysting Array limit, as described here:

https://github.com/strongloop/loopback/issues/2824

However, how can this be set in Loopback 4?

const app = new BackendLb4Application(options)
app.set // not available

Also the options, only allows for the settings of the requestBodyParser, not the express querystring (qs), which it is using.

Have you tried to stringify your filter before sending it to loopback 4 ?
