Research direction
Start by reproducing the error when using MetaMask's add-chain flow, including the attempt through chainlist.org, and inspect the attached screenshot for the reported context. Identify the failing add-chain path, then verify that the flow works without the “p is not a function” error and add or update coverage if the relevant test location is found.
