Rit shouldn't, could you share the flow @Tobseb ? Does it use an early stop maybe ?
TReason was broken dedicated worker. Nice fact: As soon as this issue was restored the flow actually executed successfully! 
R
Ris the dedicated worker working well for you ?
TYes, for what it is doing (and with proper configuration) it is working very well. Helped to reduce warmup! Not reduce, but overcome.
RGlad to hear, I'm hoping to improve the DX of it in the future such as maybe merging many scripts in same runtime and maybe having a dedicated worker for a full workspace
