Exclude sqlalchemy-spanner 1.12.0 from core

[amoghrajesh]

https://github.com/apache/airflow/pull/51379/files was done but that seems to have fixed it for google but seems that the core is pulling in with this dependency leading to conflicts!

Error:

Wasn't this handled in #51379 ?

I don't think core dependencies should do this exclusion something may be missing in the CI to catch the fix of #51379

[Lee-W]

is it also used in core 🤔 yep, looks like it's handled in #51379

@eladkal that PR fixes it for google only

@eladkal that PR fixes it for google only

core doesn't need spanner. It makes no sense to exclude it in core.
core gets spanner version from google so if the issue is fixed in google provider it should automatically fixed for core.
I think we are missing something here.

Looks like it hasnt been fixed properly in google

[eladkal]

Should be closed in favor of #51393

#51393 has now more detailed error description explaining where and where to fix similar problem when it happens next time
