Steps to reproduce:

1. Login to FOLIO X environment

2. Open settings → Invoices → batch group configuration

3. Choose any batch group and fill in the fields(url, port, username, password, location type, format) with correct credenentials and save

4. Remove url, port, username, password, location type and leave as it was location type and format, save it

5. Create invoice and select batch group from step #3

6. Add invoice line and pay invoice

7. Open Invoices app → Actions → Voucher export → Choose batch group from step #3 → Run manual export

Actual result: export status - Error, message - Cannot invoke "String.length()" because "this.input" is null
Expected Result: some message to show root cause as description
Cause:

Currently, if we skip the validation for spaces in the 'uploadDirectory' field, there's a high likelihood of encountering an NPE (NullPointerException):

In implementation, if uri is empty, code throws error

Approach:

We need to decide on the approach for validation. Currently, I have two options in mind:

1. Show correct description for cause.

2. Add validation for empy string for both directory and url
