no function clause matching in Elastic.ResponseHandler.process
miskolc opened this issue · comments
When I do indexing like this:
ProductDocument.index(product.id, data)
every now and then, I get this error:
** (FunctionClauseError) no function clause matching in Elastic.ResponseHandler.process/1
(elastic) lib/elastic/response_handler.ex:4: Elastic.ResponseHandler.process(%HTTPotion.ErrorResponse{message: "req_timedout"})
(elixir) lib/enum.ex:651: Enum."-each/2-lists^foreach/1-0-"/2
(elixir) lib/enum.ex:651: Enum.each/2

(mix) lib/mix/cli.ex:58: Mix.CLI.run_task/2
(elixir) lib/code.ex:363: Code.require_file/2
The indexing works( ie the document is indexed and can be search) but the script that does multiple indexing operations breaks after the first operation.
It seems that assigning the result to a variable
response = ProductDocument.index(product.id, data)
doesn't break the script after the first indexing operation but I'm not sure if this was the intended behaviour of the package.
What would be a better solution( if any)?
Hey Dragos,
Do you have a script that reproduces this problem that I could try to run?

I don't have a script because I ran that line of code in the console, but I've noticed the error happens when I run that instruction shortly after I open iex.
Also since I've initially opened this issue, I've noticed that this error also appears when I do a bulk create with too many rows( ie Elastic.Bulk.create(indexable_chunk)). If index_chunk has more that 10_000 tuples in it, I get that error, otherwise, if it's 10_000 or less I get no error and I also don't need to assign the result to any variable.
So now I think the error has more to do with the fact that ES can't handle new requests at a certain point in time, rather that what I said in my previous comment.
