Unable to create statements from XBRL documents

[chainhead]

Many thanks for publishing the finstr package!

While I was able to get this package working for XBRL documents filed with SEC, I am running into a strange error when working with XBRL documents filed with Ministry of Corporate Affairs (MCA) (India). Specifically, the xbrl_get_statments() function call fails.

# Get annual report XBRL and extract statements
options(stringsAsFactors = FALSE)
org2015Inst <- INST #the XML file from MCA website
org2015 <- xbrlDoAll(org2015Inst,cache.dir = "XBRLCache", prefix.out="out", verbose = TRUE)
org2015Stmts <- xbrl_get_statements(org2015)

And, this is the error I get.

> org2015Stmts <- xbrl_get_statements(org2015)
Error: incorrect length (0), expecting: 965
