Can you link me to the commit where the code which produced this issue is?

[gumernus]

one of these https://github.com/orgs/Bialu-Software/projects/5/views/1?filterQuery=&pane=issue&itemId=38283181

[gumernus]

just tried /getPosts without a body and this happened: @HyScript7

[gumernus]

we need the error handling 😭 (the filter should not be required i guess)

[gumernus]

it runs perfectly fine with body:

{
  "filters": {}
}

it runs perfectly fine with body:

{
  "filters": {}
}

okay i have fixed this in the routes but the error handling still needs to be done in the helper

Since I am not responsible for that part of the CRUD, I don't really know how to fix that, but since putting an empty filter works, I suppose setting the filter's default value to {} should fix this. Edit: I haven't accounted for undefined to be passed in the arguments, except for the post's update function, where we take advantage of undefined values.

well i have fixed it with this monster

let filters;

if (req.body.filters === undefined) { filters = { headline: "" } }
else if (typeof req.body.filters == "object") { filters = Object.keys(req.body.filters).length == 0 ? { headline: "" } : req.body.filters }
