Tabular data ingest failed. Unknown exception occured during ingest; R Tab File Parser: Could not obtain varQnty from the dataset metadata

Developers, note that "dat.RData" can be downloaded from the thread above.

The dat.RData file given in the thread seems like only like length-one character vector.

Unlike dta's/csv's, RData is not guaranteed to be rectangular -- most RData files in the wild aren't. So I'm not sure if it is a good default to try ingesting every RData/Rds file that comes in. See suggestion in #7249 to not ingest at all.

@kuriwaki thanks for the analysis. I trust you on what kind of RData file it is. 😄

I think we should close this issue in favor of the one you opened where we should decide just how much we want to support RData for both ingest (this issue) and download:

• Is RData/Rds download and ingest necessary? #7249

There's also an even bigger rethink of all of tabular ingest proposed here:

• Refactor and rethink the tabular ingest subsystem in v6. #8526

@WickM note that it's possible to skip ingest via API, if you'd like:

• 8525 ingest optional skip #8532

Here's a request to be able to skip ingest via UI (a "skip ingest" checkbox)

• File Upload: Allow users to skip ingest as tabular data. #2199
