This issue is to track service side bug (seen on 4/22). This can be reproduced by sending a multi-page input with a blank page and passing include_text_content=True. There is an off-by-one page index error due to the blank page not being returned with the results.

Copy/pasted issue explained to service team:

I trained on a 3 page document in which page # 2 was completely blank. When I analyzed my form, I got back results in pageResults and readResults, but only for pages 1 and 3 (list of length==2). My call to analyze had the include_text_details=True, however, when I attempted to resolve the pointers in the SDK I got an out-of-index error.

I found that elements references in the pageResult for page # 3 were referencing the readResult like this, for example:

"#/readResults/2/lines/30/words/0"

Since readResult was returned as a list of 2 items, indexing into readResults[2] does not exist.

Edit: fix tests that work around this once service deploys version fixing this bug
