# Troubleshooting

This guide offers insights and solutions for common errors encountered in Odoo application development.
Understanding these errors and knowing how to address them efficiently is crucial for maintaining a smooth development process.

**Error: Field “x” does not exist in model “y”**

   1. Confirm the field's presence in the model.
   2. Ensure the Python file is listed in `models/__init__.py`.
   3. Verify the existence of `from . import models` in the `__init__.py` file.
   4. Consider upgrading the module.
   5. Double-check the field name for any spelling errors.

**Error: Unable to install module “x” due to an unmet external dependency: Missing Python library “y”, “z”**

   1. Execute `pip install -r requirements.txt` to install the module's required Python libraries.
   2. If specific libraries are mentioned in the error, install them individually using pip.

**Error: Invalid field “x” on model “y”**

   1. Ensure the field exists within the model.
   2. Restart the Odoo server and then upgrade the module.

**Error: Some modules are not loaded, potentially due to missing dependencies or manifests: [“x”]**

   1. Check if the module is located in the `custom/` or `custom/src/` folder. If absent, add the module, restart the Odoo server, and attempt reinstallation.
   2. Confirm the existence of the dependency module of the missing module in either the `custom/` or `custom/src/` folder.

**Error: Inconsistent module states, possibly due to missing dependencies: [“x”]**

   1. This issue often arises when a dependency of the “x” module encounters an error.
   2. Explore and rectify errors in other related modules.
