Standard Logic App Setting Runtime.Backend.VariableOperation.MaximumStatelessVariableSize has no effect.

Question

Standard Logic App Setting Runtime.Backend.VariableOperation.MaximumStatelessVariableSize has no effect.

Simon Norton 0

I have a Standard Logic App with a Stateless workflow attempting to load a CSV file with 23,000 records into an Array. However, changing the configuration setting for Runtime.Backend.VariableOperation.MaximumStatelessVariableSize large enough to accomodate the file has no effect. If I open a new browser, I see the updated setting of 5000000 in the configuration settings, but the workflow still gives the error:

VariableSizeLimitExceeded The variable 'CSVArray' has size of more than '2151074' bytes. This exceeded the maximum size '1024' configured.

Did I overshoot a hard-limit, or just do something wrong in the configuration settings?

Note: as I understand things from my Azure admin, I have to use a Standard to be inside the secure subnet, so a Consumption Logic App is not an option :(

Many thanks for the help!

Simon

Hi Simon Norton,

Thanks for using Microsoft Q&A !!

Are you updating the configuration in configuration settings?

As per the documentation, the configuration - MaximumStatelessVariableSize needs to go to host.json and not in the app settings, as mentioned in the below documentation - Edit runtime and environment settings for Standard logic apps - Azure Logic Apps | Microsoft Learn.

Below is a sample host.json for increasing the variable size limit from 1024 to 2048 characters. User's image

Please let me know if you have any questions.

Thanks

Saurabh
