Hey - did you change the code from marketplace version 3.5.19 in the last few hours?
We are seeing new behavior in the bid history widget that was not present previously, with no version change from our side. Seems like the current version of the code was updated?
Actually looks like a change to the backend server - the /bids endpoint is giving back an object for bidderENS instead of a string, and the frontend widget code was not adapted to handle it (or at least version 3.5.20 not published yet)
