Looking into it.

Any progress on this issue?

I’m receiving this error in my code as well, and poked the agent to look at it. Essentially, v1 and v2 of embedding is supported in the geolocation libraries, but v1 was removed from the codebase I’m working with at 3.38.3. It’s failing because it can’t find the import code for v1. So the suggested fix is to remove the v1 support in the geolocation code to compile successfully. Instead, I’ve created a pre-compilation task to patch out the v1 code before building so I can still nab updates for the geolocation software but not manage my own fork.

I just put this in, so I haven’t done a full test on the app, but with regards to build success, this was successful.

yea, that old v1 code simply needs to be deleted.
