getting an error Converting circular structure to JSON when using http node which sets (msg.xxxxx)

[sudoritz]

Im not sure if the bigssh node supports being able to send other parent msg.{xxxx} and being able to pass them through the flow.

when i do a delete msg.req and msg.res it seems to work but

I then lose my http in/out ability.

a quick workaround i did was set msg.req / msg.res to flow.req flow.res and then when done i flip them back to the msg.res msg.req

Hello,

Do you have a biglib version up to date? I’ve made a change on Feb 18th in order to let messages flow though the big nodes

i did jump into my node-red docker instance to npm install node-red-biglib (i still seemed to have the issue)

[Jacques44]

can you give me the version you are using?

Hello,

I tested your flow. It was a bit difficult to find what does your POST send back..

I'm not able to get the error you've got. Sorry

[onedr0p]

No worries, I got it working by just setting res and req to empty before your plugin gets to them.
