I have some postman flows with more than 20 API requests in it.
When I run these flows which have more than 20 API request using postman agent, the flows are not running.
Getting the error “Uncaught (in promise) Error: Merlin worker not available”.
Please refer to below screenshot.
Note: I’m able to run the same flows in the cloud agent though. But the maximum number of cloud agent calls per month limited to only 1000.
It’ll be appreciated if anyone can provide a solution for this.
Welcome to the forums!
I’m trying to reproduce this issue.
Hi Daniel Kimmelmann,
Thanks for your reply.
Does it happen consistently?
Reply: Yes it is happening consistently. You can reproduce the issue by creating a flow with more than 20 API requests.
Are you using the Desktop or browser agent when it occurs?
Reply: I’m using Desktop when it occurs.
But if I use Cloud agent the same flow is working fine for me.
Is there anything else in your flow other than 20 Send Request blocks?
Reply: Along with 20 send request blocks we have some output blocks and evaluate blocks as well.
I haven’t been able to reproduce this, but i’m speaking with our backend team about it nonetheless.
Hi @flows-daniel ,
I presume the issue is because the no. of workers allocated to execute the api calls are limited and getting that error when the collection has more than 20 API calls.
Is there any configuration in postman client to increase the number of Workers (Merlin worker) as a workaround for this issue.
Im just assuming.
We have designed lots of complex flows and everything has come to an halt with this issue.
Please advise.
I sent you a DM. I’d like to setup a screenshare if possible to help us debug this issue.
