I had this happen to several models. Even in latest 2.1.3. Fails on Depth Maps step during point cloud creation. Looking into the error I see the "Cameras have null Neighbours." After several days of trial and error, I believe I solved the problem and post here to save others the headache it cost me and hopefully have the Agisoft team implement a bug fix.
In summary, we process large datasets and noticed several images of poor alignment. We went through and deleted these images that were causing issues (mainly images of just water). We also deleted the points with grad filters but cant remember if we deleted images in this step so still may be a problem.
Tests that failed to resolve the problem
Quality: Low or High
Uniform sampling: Yes and No Still failed
Point spacing (m): 0.1 and 1m still failed
Disabled Depth filtering still failed
Calculate point colors: Yes and No still failed
Calculate point confidence: Yes yes and no still failed
Reuse depth maps: Yes and No still failed
Replace default point cloud: No and Yes still failed
My theory is the model still contains tie points linked to deleted or removed images despite them being removed and is why it is bring thing null Neighbour error. The reason I think this because if I look at the camera IDs the images with null neighbours are the ones I had removed.
Resetting the alignment didn't solve the issue. It is like they are lingering there. I am running test to confirm this theory by creating a new chunk without any removed images to test, instead of just deleting the problem images entirely. Here is the full log.

Question: Is there a way to clean the model to delete tie points that are no longer associated with any active images, or is a complete project restart necessary? I'm keen to resolve this bug to avoid starting projects from scratch and to help others who might face the same issue.
