How can you find out the paths from which Terraform is loading providers referenced in your configuration files?

To determine the paths from which Terraform is loading providers referenced in your configuration files, setting the environment variable to enable verbose logging at the TRACE level is the most effective approach. When you set TF_LOG to TRACE, Terraform produces detailed logs that include information about the loading process of providers, such as the exact file paths it is accessing. This level of detail allows you to see any errors or issues related to provider discovery and helps ensure that the correct providers are being utilized in your configuration.

Utilizing the TRACE logging level helps detect where Terraform might be looking for providers that may not be properly configured or are missing. This is particularly useful in complex environments where multiple configurations may exist, and understanding how Terraform resolves dependencies can help in troubleshooting potential misconfigurations.

The other options do not provide the same level of insight into the provider loading process. While setting TF_LOG to INFO can yield some useful information, it does not provide the granularity of detail that TRACE offers. Checking the default provider path might offer some structural insight, but it lacks the dynamic feedback on the loading activities during a Terraform operation. Running the command without any flags provides no additional information regarding the provider paths, limiting your ability to diagnose provider loading issues effectively.
