Search Kit: "Combine text" field transformation seems to break output
When changing a field transformation to Combine text, such as for doing something simple of Last Name, First name, it breaks the output. That is, I get a flash and then nothing appears in the results. When I switch it back to no transformation it works.
I made sure to test it again with a fresh install of 5.46.x and replicated it.
I didn't see anything meaningful in the console.log (not sure if there's a debugging option). The only thing I saw was a persistent 500 error when attempting to reach https://XXXX.XX/civicrm/ajax/api4. Which I don't get without the field transformation.
Actually, I just replicated it on a dev site on a different server (wasn't sure if it was related to Lando). This site was running 5.43.x. This one gave a bit more information:
