Hello,
I am getting the following error. Code is also mentioned below.
%UndefinedFunctionError{arity: 0, function: :offset, message: nil, module: nil, reason: nil}
{offset, _} = Integer.parse(headers["upload-offset"]). # headers["upload-offset"] returns a valid result everytime. "0", "452342" etc
upload_info = UploadCache.get(identifier)
if offset != upload_info.offset do. # here it crashes and throw the error.
... # doing something here
else
This does not happen every time. I found this issue in the production sometimes and I am not even able to reproduce this on my local machine. Can anyone give their inputs in what scenarios, this type of error can occur?
