[Bug] Openbb 4.5.0 cannot import name 'OBBject_EquityInfo' from 'openbb_core.app.provider_interface'

[eduardcmp]

Describe the bug
I was using openbb 4.3.5 version and everything ran smoothly and when I tried to update version to current 4.5.0, a weird error trying to import OBBject_EquityInfo from openbb_core.app.provider_interface when calling fundamental endpoints from openbb. Is anyone familiar with this object? it doesn't seem to appear at all in the code

To Reproduce
I use the following pyproject.toml, then poetry lock and then i deploy a container with docker that runs the poetry install. I have checked inside the container and the libraries versions are created succesfully: openbb 4.5.0 and openbb-core 1.5.6

I share the two pyprojects, since the one in the service references to another internally created library with openbb as dependency:

This is almost certainly race condition inside your Docker.

If you are using the Python Interface, you have to build it during the build stage, immediately after installing, and before you ever attempt to import it.

openbb-build

You would need to share the code that is being run to build the container and then to import the OpenBB package.

[eduardcmp]

Update: I solve it with a dirty solution: adds missing aliases (OBBject_EquityInfo, etc.) by pointing them to OBBject (the only exported in provider_interface.py) at import time.

Summary:

ImportError when using generated equity endpoints. Example traceback:
From openbb/package/equity.py: from openbb_core.app.provider_interface import (OBBject_EquityInfo, OBBject_EquityScreener, OBBject_EquitySearch, OBBject_HistoricalMarketCap, OBBject_MarketSnapshots)
Fails with: ImportError: cannot import name 'OBBject_EquityInfo' from 'openbb_core.app.provider_interface' (...)
Observed that openbb_core.app.provider_interface in 1.5.6 exports OBBject only; none of the OBBject_* aliases are defined.
Repro steps (minimal):

1. pip install openbb==4.5.0 openbb-core==1.5.6 (Python 3.12)
2. python - <<'PY'\nfrom openbb import obb\nobb.equity.dividends(symbol='AAPL')\nPY
3. ImportError as above.
   Expected: Generated client modules shouldn’t reference missing symbols; either provider_interface should expose those aliases or the generated modules should import the right names.
   Not cache-related: a full clean rebuild in docker with no cache still shows the missing symbols; no occurrences of OBBject_EquityInfo exist anywhere in installed site-packages.
   Workaround we used: before importing OpenBB, inject aliases in openbb_core.app.provider_interface:
   setattr(_pi, 'OBBject_EquityInfo', pi.OBBject) (and similarly for Screener/Search/HistoricalMarketCap/MarketSnapshots)
   Provide getattr fallback to return OBBject for any OBBject* name

[deeleeramone]

You have to do this while the container is being built and let it complete. Your issue appears to be the result of an interrupted build of the static assets.

Please share your DockerFile, and the code responsible for importing and using the package in your application.

[eduardcmp]

I tried your approach, but still was not working, final workaround implemented was to add a getattr fallback that returns an OBBject in dockerfile after poetry install and openbb-build:

# Install dependencies
RUN poetry install
RUN poetry run openbb-build
RUN poetry run python - <<'PY'
import openbb_core.app.provider_interface as pi
from pathlib import Path

p = Path(pi.__file__)
src = p.read_text()

if "def __getattr__(" not in src:
    src += """

# --- OpenBB compatibility shim (build-time) ---
# openbb (4.5.0) generated modules import many names like `OBBject_EquityInfo`
# from this module. In openbb-core 1.5.6 these typed aliases are not present,
# causing ImportError at import-time. Provide a generic fallback for any
# `OBBject_*` symbol to keep runtime working.

def __getattr__(name: str):
    if name.startswith("OBBject_"):
        return OBBject
    raise AttributeError(
        f"module 'openbb_core.app.provider_interface' has no attribute {name!r}"
    )
"""
    p.write_text(src)

print("provider_interface patched:", p)
PY

Now working but doesnt look clean

[deeleeramone]

--- OpenBB compatibility shim (build-time) ---
openbb (4.5.0) generated modules import many names like OBBject_EquityInfo
from this module. In openbb-core 1.5.6 these typed aliases are not present,
causing ImportError at import-time. Provide a generic fallback for any
OBBject_* symbol to keep runtime working.

These imports do not exist: OBBject_EquityInfo and there is no "shim" required.

Regardless, I cannot recreate. If you would like some help debugging your code, please share a link to the source code or paste the entire Dockerfile and all relevant code.
