I think it may be related to this PR

Thanks for reporting this @xiandong79, I'll investigate ASAP. I should have added a test to the dataframe_client for this.

I can take a look too if that helps, I haven't come across that issue though.

[xiandong79]

the version 5.2.3. works well

[hiksuman]

I'm having the same issue querying from both Influx 1.7.10 and 1.7.7
Interestingly with Influx 1.0.2 the bug is not present.

[sebito91]

There are a lot of differences between 5.2.3 and 5.3.0, which is why we stepped a minor release instead of point-release.

@hrbonz if you want to take a look that would be AWESOME!

I am getting a different error, but seemingly from a similar place.

I can confirm query with chunk=True does not work on 5.3.0.
