Logic App Standard InApp FTP connector ServiceProviderTriggerStateTooLarge error

Tadas 5

Using InApp FTP connector with Logic App Standard. Workflow is triggered using "When a file is added or updated". Trigger fails with the following information:

Fired
False

Status
Failed

Code
ServiceProviderTriggerStateTooLarge

Outputs link
No outputs

App insights shows the following information:

{"code":"ServiceProviderTriggerStateTooLarge","message":"The size of the trigger state returned by the service provider with trigger name 'When_a_file_is_added_or_updated' has length '22478' characters which exceeds the maximum limit of '10240' characters. Please contact the service provider to get this fixed."}

Does it mean that FTP connector output is too large (since output link is empty)?

How to fix non working workflow?

I've tried workflow with mine FTP and it worked fine, but it doesn't with our customers FTP.

@MayankBargali-MSFT no need and seems like I figured it out. Looks like I have to override value for

ServiceProviders.MaximumAllowedTriggerStateSizeInKB

in app settings but not

Microsoft.Azure.Workflows.ServiceProviders.MaximumAllowedTriggerStateSizeInKB

as you've suggested. Overriding in host.json took no effect, but ServiceProviders.MaximumAllowedTriggerStateSizeInKB looks promising and not getting errors now.

Furthermore an error was about 10240 limit so it's 10KB. Where the default limit for Microsoft.Azure.Workflows.ServiceProviders.MaximumAllowedTriggerStateSizeInKB is 1KB and limit for ServiceProviders.MaximumAllowedTriggerStateSizeInKB is 10KB

@Tadas Thanks for reaching out. It looks like you haven't updated the Microsoft.Azure.Workflows.ServiceProviders.MaximumAllowedTriggerStateSizeInKB configuration in your standard logic app. Can you try to set this value to a higher value as per your file size and see if it helps to you to resolve the issue?

In case if you set it to some other values and see the same error with max limit of 'xx' characters then you need to further tweak the value.

Important: Based on your storage size, avoid setting this value too high, which can adversely affect storage and performance.

In case the above doesn't help then please let me know.

Update:

Correct setting is ServiceProviders.MaximumAllowedTriggerStateSizeInKB

@MayankBargali-MSFT thanks for your reply, but we need more info on how to override this default limitation if it's possible at all. Our host file:

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle.Workflows",
    "version": "[1.*, 2.0.0)"
  }
}

Our logic app is defined using bicep and appSettings doesn't contain anything unusual or any overrides related to ...MaximumAllowedTriggerStateSizeInKB We've tried to override by adding to configuration:

{
    "name": "Microsoft__Azure__Workflows__ServiceProviders__MaximumAllowedTriggerStateSizeInKB",
    "value": "23000",
    "slotSetting": false
  }

with no luck. Still getting the same message with default 10240 limitation: The size of the trigger state returned by the service provider with trigger name 'When_a_file_is_added_or_updated' has length '22538' characters which exceeds the maximum limit of '10240' characters. Please contact the service provider to get this fixed.

@Tadas The same document cover how to update any of the listed setting using portal, VS Code (local.settings.json) and CLI.

If you are doing from portal you need to create a new New application setting with the name Microsoft.Azure.Workflows.ServiceProviders.MaximumAllowedTriggerStateSizeInKB and value as your custom value

@MayankBargali-MSFT According to documentation Microsoft.Azure.Workflows.ServiceProviders.MaximumAllowedTriggerStateSizeInKB is a host.json setting so I've updated as described here but still same 10240 limit.
I've updated Kudu -> site -> wwwroot -> host.json and restarted the logic app.

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle.Workflows",
    "version": "[1.*, 2.0.0)"
  },
  "extensions": {
    "workflow": {
      "settings": {
        "Microsoft.Azure.Workflows.ServiceProviders.MaximumAllowedTriggerStateSizeInKB": "23000"
      }
    }
  }
}

@Tadas Please send an email to “Attn:Mayank” to AzCommunity[at]Microsoft[dot]com referencing this thread along with your subscription ID and logic app name so I can validate if the setting are reflected correctly or not to assist you further.

@Tadas Ohh my bad. Looks like I confused with the setting. Thanks for correcting me. Yes, that would be ServiceProviders.MaximumAllowedTriggerStateSizeInKB
