Hi, I have an HTTP request which fails with the error - Cannot write more bytes to the buffer than the configured maximum buffer size: 104857600. Screenshot 2023-04-04 at 11.52.00 am

To fix this I even tried allowing chunking as well, but I still get the same error. How do I fix this? Screenshot 2023-04-04 at 11.52.26 am

@Vivek Komarla Bhaskar Thanks for reaching out.

If you are using consumption, then there is no configuration that supports increasing this limit of HTTP connector.

In case if you are running your workflow in a standard logic app then this configuration can be changed. By default, the max size content is configured as 104857600 bytes as documented here for standard logic app.

To increase the size of for the build in HTTP trigger you need to configure the Runtime.Backend.HttpOperation.MaxContentSize in the application setting on your standard logic app.
Further you may hit the limit value of inputs and outputs that the trigger/action. So, you need to configure the settings for Input and Outputs as mentioned here.

These configurations are only supported/valid for standard logic apps. In consumption logic app there is no way to configure any setting or increase the default limits.

Hi, Our current usage makes standard logic apps too expensive. Are there any other options to accomplish this? Could Azure Event Hubs be an option? In addition to the above, For POC I have created a standard logic app and trying to make configuration changes as you suggested but I can't find any setting with the name - Runtime.Backend.HttpOperation.MaxContentSize

The proposed solution does not work. I created a New Application setting Runtime.Backend.HttpOperation.MaxContentSize with a different value.

In case someone is still struggling with this.

we need to update host.json file -> Logic App Standard -> Search for Advanced Tools -> Click on Go.

Debug Console-> CMD || Power Shell -> Navigate to site\wwwroot> Host.json edit it.

Add below :

,

"extensions": {

"workflow": { "settings": { "Runtime.Backend.HttpOperation.MaxContentSize": "<value you desire>" } }

}
