It looks like this may be related to pull request [#1896](https://github.com/gramps-project/gramps/pull/1896) - “New indexes for big databases in the narrative web report”. ---

Thanks Nick My Family Tree is approx 18000 individuals, tried increasing the value for the index from 500 to 2000 made no difference. Will spend some more time on this and get back to you phil ---

We have a problem here. Did you modified the sources ? The following instruction does not exist at line 557: ```python max_rows = max_letter_rows[bletter] ``` ---

Serge I run 2 PC’s a Pi5 running Bookworm and an i5 running LMDE6 both have Version 5.2.4 with your mod for incl roles. Both do have that line as described at line 557. Neither has been updated or changed in the last 3 months. I have subsequently run the report on the Pi using a simplified tree with no problem. I need to retrace all my steps to reproduce the error will get back to you phil ---

Serge Apologies for delayed response. My usual working method is to create a backup on my LMDE PC and store it on my NAS, I then import it to my Pi5. For some reason (senior moment) I had copied my grampsdb folder on my LMDE PC and then pasted this into my Pi5. It is this version that brings up the error. So must be the difference in setup between LMDE and Bookworm that causes the issue which I have no inclination or desire to investigate further. Please do not worry about this further made a note to self only do the “import” in future. phil ---

You should apply a patch for this. It was commit [a8885d5855d901f833064d1b69ec45f7b8cfe79d](https://github.com/gramps-project/gramps/commit/a8885d5855d901f833064d1b69ec45f7b8cfe79d) ---

Two problems with that commit for me 1. It is for Ver 6 not explicitly for 5.2.4 2)“Fix narrative web report crash with empty an database.” My database is fully functional and not empty as far as I am aware phil ---

I am feeling particularly dense today but could you point me in the direction of the original report that caused you to make this patch. The fault occurred as a result of my own actions of copying and pasting a database rather than importing and when using the importing route I do not have an error, but the copying and pasting route gives an error however this database is perfectly usable other than for the Narrative Web Report. Thank you for confirming that the patch is suitable for 5.2.4 phil ---

This was one way to create the bug. I can say you can safely apply the patch I proposed. This patch only remove the max\_rows variable which is the cause of your problem. You can see what it do with the command: `git show a8885d5855d901f833064d1b69ec45f7b8cfe79d` ---

I think I would like to close this off. Firstly by thanking Serge, Nick and Brian for their assistance/forbearance for trying to resolve a situation of my own creation (should have known better). The current situation is that I have applied Serge’s latest commit with no issues on existing or imported databases. The database I copied and pasted now does not show an error when running as expected but the final report has no contents whatsoever yet the db is clearly populated. phil ---
