We report on the results of the first search for the production of axion-likeparticles (ALP) via Primakoff production on nuclear targets using the GlueXdetector. This search uses an integrated luminosity of 100pb$^{-1}\cdot$nucleon on a $^{12}$C target, and explores the mass region of 200< $m_a$ < 450 MeV via the decay $X\rightarrow\gamma\gamma$. This mass range isbetween the $\pi^0$ and $\eta$ masses, which enables the use of the measured$\eta$ production rate to obtain absolute bounds on the ALP production withreduced sensitivity to experimental luminosity and detection efficiency. Wefind no evidence for an ALP, consistent with previous searches in the quotedmass range, and present limits on the coupling on the scale of $O$(1 TeV). Wefurther find that the ALP production limit we obtain is hindered by the peakingstructure of the non-target-related dominant background in GlueX, which wetreat by using data on $^4$He to estimate and subtract these backgrounds. Wecomment on how this search can be improved in a future higher-statisticsdedicated measurement.
