Hi @progprob,

Thanks for opening this issue. The minimum supported agent version for ddtrace>=1.0 is v7.28 (version policy. Can you confirm your agent version?

To resolve this issue we recommend upgrading your datadog agent to the latest version (upgrade docs, releases). If this is not an option for you you can use the previous encoding format by setting the following environment variable: DD_TRACE_API_VERSION=v0.4 docs

Let us know if those options work for you 😄

Hello @mabdinur and that's for the quick reply. I'm actually using version 1.7.2. However, by setting DD_TRACE_API_VERSION=v0.4 as you suggested I got rid of the issue and for that I'm super thankful ! I'm closing the ticket for now then.
