Error: Another process has added 'SOOrder'

[jelle_webcompany_nl]

We retrieve a order from an external system and send it towards the visma.net application we receive the following response from visma, 

Error: Another process has added 'SOOrder'

 But that is not possible as we are the only one connecting to that environment.

the strange behaviour is that this doesn't occur all the time, some orders go through and some don't go through. 

how to resolve?

That message is the default message the API returns when something in the backend crashes.

It has nothing to do with concurrency or timing.

It might be temporary and a retry will work but it could also be your request having an invalid value.

Hi Jelle, any chance implementing retry mechanism or putting some delay between the requests if ain't no ? 

[jelle_webcompany_nl]

The delay doesnt work, increased the delay to 0.5 seconden between requests, but it goes wrong on the post 

"request type":"POST",

"endpoint":"https://integration.visma.net/API/controller/api/v1/salesorder"

We build in a retry mechanisme, we can try and put a sleep state between the requests
