Request for Library Update: Compatibility Issues with Modern Dependencies (protobuf, OpenTelemetry)

[MG1093]

Hi team,

First off — thank you for your work on this project!

I'm interested in converting your ctrader-open-api library into a LangChain/CrewAI Tool, but I've run into some compatibility issues when trying to install it alongside newer libraries.

It seems the current version of ctrader-open-api has strict dependencies on older versions of protobuf (e.g., protobuf==3.19.1 or 3.20.1), which conflicts with other tools like crewai[tools]>=0.114.0 that require protobuf>=5.0,<6.0 through dependencies like opentelemetry-exporter-otlp-proto-http.

Here’s the error summary:

ctrader-open-api depends on protobuf==3.19.1 or 3.20.1.

opentelemetry-exporter-otlp-proto-http (required by CrewAI) depends on protobuf>=5.0,<6.0.

As a result, it's currently impossible to install both ctrader-open-api and the latest crewai[tools] together.

Question:

Is the library still actively maintained?

If so, would you consider updating ctrader-open-api to be compatible with newer versions of protobuf (>=5.0,<6.0)?

These fintech libraries for small players are always dead when I arrive at them. Great.
