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?

for example, simple function is\_presented even with try-catch

```julia
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

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

[42] signal (6.-6): Aborted
in expression starting at none:0
unknown function (ip: 0x7f9524140d3c)

count_documents at /home/worker/.julia/packages/Mongoc/tJNDW/src/collection.jl:297 [inlined]
is_presented at /coinstrategies/history/src/StorageNew.jl:296

```

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`
