Getting error while reading/writing a file created by azure functions v4

Question

Getting error while reading/writing a file created by azure functions v4

abhinovpankaj 1

I am creating a reporting service, which generates a report based on data from Mongo db and images etc.

I have created http trigger which works just fine and creates the report file locally without any issues.

However, it fails to create the report file when deployed to Azure functions.

I have checked the folder, the file is not created. Could you please help me with this.

I would try replacing the spaces in the file name with underscores to see if that makes a difference.

Sure. Let me know how it goes and if you have any logs that confirms that file was created successfully and other details as requested in my previous comment.

@abhinovpankaj As per the logs it looks like the file was not created successfully. Can you please check your application logs/application insights logs to validate if the file was created successfully. Please validate if you have handled an exception while creating the file and this could be the reason the exception is not thrown. I can see the information logs "inside document save" so looks like it may be inside the method but cannot confirm if the file was created. Do you have any dependent library that you are using in your azure function?
