Describe your environment (please complete the following information):

• OS: [e.g. iOS]
• Haystack version:
• Integration version:

[julian-risch]

We released version 0.4.1 of our uptrain-haystack integration now, where we pin the uptrain version to 0.5.0. The issue does not occur with that older version of uptrain and integration tests are very slow but run through.
