Getting Exception: TypeError: 'function' object is not subscriptable

Question

Getting Exception: TypeError: 'function' object is not subscriptable

GURUVANANTHAM Guru-Mohan 1

Dear Team,

I'm trying to execute a custom python script inside my Azure Function App and getting function object is not subscriptable error in exceptions.

I've verified that there is no function name having the same name as object. It is really too difficult to figure out the error.

Could any one suggest on this?

Regards,
Guru Mohan G

@GURUVANANTHAM Guru-Mohan Can you share the full stack error message. I will suggest you to verify if there are any packages that you are using in your function app that may cause this issue. Please verify if you have added your packages in requirement.txt

If it is possible it will be great if you can share your sample code reproducing the issue along with your requirement.txt and init.py file will help in assisting you further.

@GURUVANANTHAM Guru-Mohan Requirements.txt file is used you want specific packages to be installed on your azure function. The packages name that you mentioned in Requirements.txt is installed using the pip command in your function app.

As per your file, I can see only requests and azure.storage.blob package available. As the other module name that you have specified couldn't install/found using pip therefore in the exception traces you can see there is an issue in installing those packages.

wallix_module_py  
wallix_register_py  
get_vault_secret_new_py  
requests  
azure.storage.blob
