Thank you so much for checking out searchbuildR! I am wondering why this error occurs for you. Should this not be handled by line 43 req() without any further checks necessary?

That would make sense to me! I am not sure but it seems to be because of the switch() which is looking for either txt or ris file. Shiny can be a bit weird about how it runs code (not always in what we think is "order")
