GrpcApiError - "Failed to execute grpc AEDT command: GetProperties"

[chamanth-vct]

Hi,

I frequently encounter the following error while using pyaedt:

GrpcApiError: Failed to execute grpc AEDT command: GetProperties

Unfortunately, I have been unable to determine the exact cause of this issue. Additionally, I have not been successful in reproducing the problem with a sample file.

Request:

Could you provide any guidance or insights into:

• Potential causes for this error.

• Best practices for debugging such issues.

• Any known scenarios where this might occur.

Any help would be greatly appreciated!

Hi @chamanth-vct ,

I suggest using an IDE like PyCharm or VS to debug your code, then it will be easy to find where this error is happening. For instance, in PyCharm, I can see all places where GetProperties is used:

It is difficult to predict where this is happening for you, so please try to reproduce it and send a snipped code.

Hi @Samuelopez-ansys

Thank you for your suggestion. I was able to locate the source of the error. It appears when attempting to access the material name of an object attribute using the following code:

desktop = ansys.aedt.core.Desktop()
prj = desktop.load_project(file_path)
model = prj.modeler
object_names = model.object_names

for item in object_names:
    geo_obj = model.get_object_from_name(item)
    try:
        geo_obj.material_name
    except Exception as e:
        print(item)
        print(f"\t{e.__class__.__name__}: {str(e)}")

Unfortunately, I'm unable to share the specific model where this issue arises. However, I did notice an interesting detail: the error only occurs for certain objects that are included in the object_names list but are not visible in the GUI.
