Looking into it.

Any progress on this issue?

[tribolumen]

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.

[christocracy]

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

Sorry for commenting on an old ticket but did this get resolved ? I'm also getting the same error with a similar setup.

[joelfunk]

I've all but given up on this package. Can we be clear about what we need to do to resolve this issue? How do we "delete that old v1 code"? Shouldn't there be an update to this library?

[fixatd]

I'm also stuck on what that meant. I've been searching the local copy of the library in case I could try deleting something but no luck.
