These issues are what I like to call developer paper cuts. They are points of friction where something does not function as expected but occurs infrequently, leading to a lack of prioritization for investigation. One of these developer paper cuts is the occurrence of the HTTP 502 response code from services operating on the platform. In this post, I will detail our investigation into this issue, highlight some known causes of the 502 response code, and provide tips for debugging similar issues.</p> https://old.bill.dev/notes/getambassadorsrevsplatformengineering/ Sat, 07 Oct 2023 15:09:26 +0100hello@bill.dev (Bill) https://old.bill.dev/notes/getambassadorsrevsplatformengineering/ <figure><img sizes="(min-width: 35em) 1200px, 100vw" srcset=' /notes/getambassadorsrevsplatformengineering/TeamStructure_hu_13c939acc5be5764.png 500w , /notes/getambassadorsrevsplatformengineering/TeamStructure_hu_49373ada72705c46.png 800w , /notes/getambassadorsrevsplatformengineering/TeamStructure_hu_8f755394767a1f5a.png 1200w , /notes/getambassadorsrevsplatformengineering/TeamStructure_hu_693dc329a514ad82.png 1500w ' src="https://old.bill.dev/notes/getambassadorsrevsplatformengineering/TeamStructure.png" alt="Organisation chart showing that multiple application teams are supported by both Platform Engineering and Site Reliability Engineering teams.
