Null service handle error

[e-ercan]

Hi, thanks for the package.

I'm sure it's my fault but I've tried everything I can think of but I'm unable to get it working.

I couldn't find anyone with the same issue or anything related to blpapi that helped

I've installed according to instruction, matched the versions of the C++ SDK (3.14.1xx) to the python version 3.14 and moved the blpapi ddls to the correct place

When I try to run the examples I think xbbg.blp isnt able to establish a connection properly

I tried manually using blpapi to establish a connection which appears to work (despite the error returned, session.start() returns true)

I tried looking through conn.py but wasn't able to resolve it myself

Interestingly the live function appears to work

Not sure what to try next, I've tried reinstalling from scratch but no luck

Thank you for any help, much appreciated

Which version are you using? I just tried below two (date of bdib is 2019 cause we can only get intraday data within half an year) and both work (you can add log='debug' to see what exactly have been sent to Bloomberg section):

In your manual connection code, can you try below to see what happens:

req = ref.createRequest('ReferenceDataRequest')

Looks like something is wrong ReferenceDataRequest.

Thanks for the quick reply

I'm using the latest version of xbbg installed via pip, same with blpapi, and the 3.14 major version of the Python and C++ SDK downloaded from WAPI on Bloomberg

This is the ReferenceDataRequest and the output which seems to have worked

The result it returns for PX_LAST is 7 so I think I'm managing to connect to the API and haven't messed up the install of blpapi (I think)

The next image is the error I get on the first attempt to execute the call

This image is the error I get every attempt afterwards

Thought that might be useful

Thanks

Found the problem - there are some API changes of blpapi from 3.13.1 to 3.14.0. I was using 3.13.1 before.

You can download the C++ experimental API from Bloomberg website (currently still 3.13.x) and install 3.13.1 as temporary solution:

pip install blpapi==3.13.1 --index-url=https://bloomberg.bintray.com/pip/simple

Will update the package later - guess will take some time.

Thank you, I really appreciate it

Easier than I thought. Now it should be ok.

Kindly update and check if it works. Thx

Working perfectly now, cheers :)
