“Unmeaningful” research experience?

I started in the lab right when my PI was starting a new project, and she kinda handed it over to me. I produced some data which did not support the hypothesis. To get this data it took 6 months (300 hours) of learning, failing, then finally getting reproducible results. The next step is to gather and grow yeast mutants under different conditions to find the transcription factors of the gene of interest... but my PI doesn’t want to pursue that, not yet at least, because it’s a huge... “Unmeaningful” research experience?
