Custom AI behaviour tree

I’m presently working with Unreal Engine 4 on a project in which I’m attempting to develop a custom AI behaviour tree for my game’s adversaries. Nevertheless, I’ve been having trouble completing this activity due to a recurring issue.

When I try to build my behaviour tree, I receive the error code 0x80070057. This problem displays in the console output, and I am unable to test or run the game until it is rectified.

I tried searching for the problem number online, but the results are hazy and don’t appear to be tied to Unreal Engine in particular. According to what I’ve seen, the error code appears to imply a broad problem with wrongly given input or parameter values.

I double-checked my behaviour tree as well as all of the input values and parameters, but I couldn’t discover any obvious errors or discrepancies. Learn about doubly linked lists again from here to make sure I’m not missing anything. I’ve also attempted to simplify the behaviour tree by eliminating any extraneous pieces, but the mistake remains.

I’m not sure what further to do at this point, and I’m scared that this problem will prohibit me from finishing the project on time. I’m hoping that someone with greater knowledge of Unreal Engine and behaviour trees can assist me in diagnosing and resolving this issue so that I may keep working on my game.
