Mongoc errors in container with julia 1.9 libmongoc driver

General Usage
1

bHello! Everything was fine on my PC (I use Julia 1.8) but I needed to deploy the app in a container and could not find the official 1.8 image so I installed 1.9.
The problem appeared with Mongoc package. I have the same versions in PC and container but errors were like

  • mongoc_collection_find_with_opts (collection couldn’t be NULL) for Mongoc.find
  • mongoc_collection_count_documents (call couldn’t be NULL) for Mongoc.count_documents
  • etc

It seems that package Mongoc is only a wrapper for libmongoc (Mongo C driver). I use Windows so how I can check the version of this driver in Windows and put it in my docker file for Debian, it’s a nonsense error that occurs even if I wrap Mongoc.find with try-catch handling…
Or maybe the problem is in Julia versions?

Could you post thr entire actual error with stack trace?

for example, simple function is_presented even with try-catch

function is_presented(storage::MongoStorage, symbolname)   
    result = true
    try
        bson_filter = Mongoc.BSON("symbol" => symbolname)
        result = Mongoc.count_documents(storage.common_data, bson_filter) > 0
    catch e
        println(e)
        result = true
    end
    result  
end

Get the error

 The parameter: coll, in function mongoc_collection_count_documents, cannot be NULL

The stupidest thing is that 296 line is inside the try-catch

result = Mongoc.count_documents(storage.common_data, bson_filter) > 0

And it always work perfectly it is one one-liner function… Was… Than I wrap it with try-catch - no reaction. All warkers were aborted and app died.

Nothing work properly. Mongoc.find get the same but with mongoc_collection_find_with_opts
