It seems the connection is getting wrong. Check the "connection" field in function.json file.
Here is the description of this field:
The name of an app setting that contains the Storage connection string to use for this binding. If the app setting name begins with "AzureWebJobs", you can specify only the remainder of the name here. For example, if you set connection to "MyStorage", the Functions runtime looks for an app setting that is named "AzureWebJobsMyStorage." If you leave connection empty, the Functions runtime uses the default Storage connection string in the app setting that is named AzureWebJobsStorage.
If it is correct, navigate to your Function app and click the Configuration under settings, check the app setting contains your storage account connection string.
On my side (by default), it is AzureWebJobsStorage:
