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?
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.
- silly question but you restarted node-red after each
settings.js change ?
- you did confirm that the flow file is indeed larger than 5mb to eliminate it being some other issue
- made sure you edited the correct settings.js 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.
