\begin{document}$ \gamma p \to K^+\Lambda(1690) $\end{document} reaction within a tree-level effective Lagrangian approach to understand the underlying production mechanisms and study the resonance contributions in this reaction. In addition to the t-channel K and \begin{document}$ K^\ast $\end{document} exchanges, s-channel nucleon exchange, and interaction current, the s-channel nucleon resonance exchanges are included in constructing the reaction amplitudes to describe the data. It is found that the contributions from the s-channel \begin{document}$ N(2570)5/2^- $\end{document} exchange are required to describe the most recently measured total cross-section data for \begin{document}$ \gamma p \to K^+\Lambda(1690) $\end{document} from the CLAS Collaboration. Further analysis indicates that the interaction current dominates the \begin{document}$ \gamma p \to K^+\Lambda(1690) $\end{document} reaction near the threshold as a result of gauge invariance. The t-channel K exchange contributes significantly, while the contributions from the t-channel \begin{document}$ K^\ast $\end{document} exchange and s-channel nucleon exchange are ultimately negligible. The contributions from the s-channel \begin{document}$ N(2570)5/2^- $\end{document} exchange are found to be responsible for the bump structure shown in the CLAS total cross-section data above the center-of-mass energy \begin{document}$ W \approx 2.7 $\end{document} GeV. The predictions of the differential cross sections for \begin{document}$ \gamma p \to K^+\Lambda(1690) $\end{document} are presented and discussed, which can provide theoretical guidance for future experiments."> Photoproduction <inline-formula><tex-math id="M1">\begin{document}${ \boldsymbol\gamma \boldsymbol p \boldsymbol \to {\boldsymbol K}^+\boldsymbol\Lambda{\boldsymbol{(1690)}} }$\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/d2864bb9-2653-4823-b506-c30fc973889c/CPC-2021-0464_M1.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/d2864bb9-2653-4823-b506-c30fc973889c/CPC-2021-0464_M1.png"/></alternatives></inline-formula> in an effective Lagrangian approach -
