More understandable error message when max_document_size has been reached

[pana87]

Expected Behavior

Understandable error message

Current Behavior

I was getting this error suddenly on every insert operation:

Error: users at responseHandler (../node_modules/nano/lib/nano.js:193:20) at ../node_modules/nano/lib/nano.js:442:13 at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

Possible Solution

I updated the max_document_size in the couchdb configs

Context

I spent 3 days trying to find out what this error meant. Maybe it would be useful for developers if the error message was a bit more understandable.

Can you check if it comes from this line? It's 442 in the error message, but something different in the current code.

If you can still reproduce the issue, can you also patch that bit by adding console.log(e) and share the output here?

I guess, this can be improved by patching streamResponseHandler; can you share a more specific message you'd expect? Like "max_document_size has been reached when/for ..."

[pana87]

I reproduced this by decreasing the max_document_size and tried an insert operation.

"max_document_size has been reached" this is a understandable error i guess. maybe we could provide the solution also like: go to config -> go to section couchdb -> add or increase max_document_size option or something like this, would be very helpful. what do you think? @YakovL

Here is the console.log(e)

Hi @pana87, good thinking about making the error message helpful, may be it can read "max_document_size has been reached, you may want to open config [what config?], ...". However, the problem here is that the error doesn't seem to be specific enough to be attributed to the max_document_size issue – can be something different in another case. May be you can try to check the response with the Dev Tools and check if it conatins anything more specific to extract? If it doesn't contain enough info, this would be an issue of the server, not that of the nano client.
