The error message correctly tells you that you have invalid characters.
Then it gives you totally useless advice that you may have mistyped it.
It neither tells you what the valid characters are, nor what invalid characters are.
It also doesn't provide a link to the documentation of how to properly create a "base output name".
Best: Accept SPACEs in File name.
The advice to check if you mistyped it is useless.
Better:
1. Provide the list of invalid characters. For space, use the word SPACE.
2. Provide what are the "valid" characters: Letters, Digits, Underscore (_).
3. Provide a link to Scheduler documentation for rules to create an output file name.
Given that the Scheduler is intended for non-developers, a useless error message is just that. My manager, who is doing the scheduling, had to send an email to me, where I had to experiment with what the invalid characters could be, then provide the validation message that should have been provided, with the work around.
For example, she entered "CCN Arkansas Heart Hospital XL"
You could have responded with: "Spaces may not be in the Output File name. Would you like it changed to: "CCN_Arkansas_Heart_Hospital_XL"? Yes-button, No-button?
