This error is clearly related to the size of the flows within the instance since I can reduce the size of the flow file (by removing a node or 2 from the flow). I've attached a screen shot of the error.
The post seems to refer nicely:

The answer is to increase the limit in express, however no matter what I've tried setting httpServerOptions has no effect. I do note that express.json and express.urlencoded are methods
Is anyone able to provide the correct syntax to set these options within settings.js?
```auto
app.use(express.json({limit: '25mb'}));
app.use(express.urlencoded({limit: '25mb'}));
```

I havent used this option but from my settings.js file the default is commented out and is defined as an object. So im guessing
`httpServerOptions: { limit: '25mb' },`
no need for app.use or anything else .. i think it should apply for all middleware
**[EDIT]**
I see there is also an option in settings for `//apiMaxLength: '5mb',`
> The maximum size of HTTP request that will be accepted by the runtime api. Default: 5mb

@UnborN tried the httpServerOptions idea but it has no effect. I did also try to increase apiMaxLength to no avail. I think this one is for http request nodes.
Any other ideas? Is there somewhere I could possibly edit this in the express modules themselves?

sorry @skipware .. have no idea .. by reading some other posts apiMaxLength should have worked.
1. silly question but you restarted node-red after each `settings.js` change ?
2. you did confirm that the flow file is indeed larger than 5mb to eliminate it being some other issue
3. made sure you edited the correct [settings.js file](https://nodered.org/docs/user-guide/runtime/settings-file)

Hey @unborN,
Short Story: it is the apiMaxLength parameter in settings.js that fixes this issue. The httpServerOptions does nothing for this issue.
When testing I had increased the apiMaxLength to 10mb but had actually used so many nodes that the flows file was bigger than the new setting. The original size of the flows file ( .../.node-red/flows\_.json was bordering on the default 5mb.
Thanks for the direction.
