IX too large GET requests with Prebid 5.6.0

[muuki88]

Type of issue

Bug

Description

When banner.sizes or the number of ad units requested get too big, then the bid request fails with a 400 HTTP status.
This is the same as #5663 , which got fixed, but somehow introduced again.

My hypothesis is that the GDPR consent string takes up a large portion of the request.

It worked with 4.43.0

Steps to reproduce

• Create a 5 ad units with 10 sizes each

Test page

• Go in mobile mode
• Go to https://gutefrage.h5v.eu/460/

Expected results

Request to casalmedia works

Actual results

Request to casalmedia returns 400

Platform details

• prebid.js 5.6.0

Other information

• Same issue as in IX error after update #5663
