Texts API: Contemporary Halakhic Problems requires chapter name

[MichaelJBerk]

When trying to use the Texts API to get the text from any volume of Contemporary Halakhic Problems without a chapter name, it doesn't return the first section of the text like it should. Instead, the API gives the error "Can not pad a schema node ref".

Sample URL: https://www.sefaria.org/api/texts/Contemporary_Halakhic_Problems,_Vol_I

If using pad=0 to return the entire book, the API instead returns the error "Can not get TextFamily at this level, please provide a more precise reference"

https://www.sefaria.org/api/texts/Contemporary_Halakhic_Problems,_Vol_I?pad=0

If I include the name of a chapter, it works fine:
