Hi @keso.  In addition to the methods you mentioned in your post I also wanted to highlight that it's possible to handle MISP log Ingestion through ingestion scripts that we provide on our GitHub repository.

These ingestion scripts are used with Cloud Run functions to accomplish ingestion and you can see the full list of supported sources and associated scripts in the repository.

Hi @vaskenh I followed the document and tried to run the scripts in cloud function. However am facing the below error

Have you ever seen something like this ?

It looks like the environment variable for your customer ID has not been set. Did you create an env.yml file and specify the file in the gcloud command deploying the function? If you are building the function in the UI, you can also fill these out in the runtime variables section.

https://cloud.google.com/functions/docs/configuring/env-var

Hi @cmorris I did tried everything as per the doc but still am facing the same error also I checked all the env.yml it's up to date with all required information 

Are you deploying via Cloud Shell or the UI? If Cloud Shell, can you share the (sanitized) command you are using?

Am using UI for the deployment

Hi @cmorris In addition to this can we import the MISP IOC to GCS and the export them into Google Scopes using custom Python Script ?

Can you try the following in place of the env.yml file as it looks like your env.yml file is not being used by the function:

1. 
   

   Open the Functions Overview page in the Google Cloud console:

   
   


2. 
   

   Click an existing function to go to its details page.

   
   


3. 
   

   Click Edit.

   
   


4. 
   

   Open the Runtime, build and connections settings section.

   
   


5. 
   

   Select the Runtime tab.

   
   


6. 
   

   Add in your Runtime environment variables.

   
   

I did and still and am still facing the same error as mentioned previously
