The error message “Index was out of range. Must be non-negative and less than the size of the collection” typically indicates that an invalid index has been used when accessing a collection, such as an array or list. Specifically, this means that the index you are trying to access is either negative or exceeds the size of the collection.

I have looked into several solutions for similar issues you might be facing, and you can try the following steps:

1.Firstly, please check that the URL you have entered for Data Lake Storage Gen2 meets the required specifications.

Here is a screenshot from the relevant documentation:

For further details, please refer to the documentation.

2.Secondly, ensure that the correct ports are open for your network/firewall.

3.Next, based on another document related to the same error, you might also consider upgrading Az.Resources to see if that resolves the issue:

For detailed guidance, please refer to the documentation.

4.Finally, you could try changing the account privileges to see if that helps resolve the problem.
