@rudreshsolanki97 Thanks for providing additional information! We will test and if required fix it asap.

We're seeing Web3 1.2.8 install, run a webpack production build, and execute correctly on gnosis/dex-react.

Going to close this but if someone has a simple reproduction case (e.g a repo with clear reproduction steps please just ping and will investigate further.)
