Unable to save Flow Designer due to REST Payload exceed error

[Bird1]

Hello,

I have a Flow Designer which need to contain about 120 If conditions. I am afraid that it will contains 300+ actions in Flow Designer, so I tried to chop each If conditions to subflow (for example: 1 subflow will contain about 5-10 if conditions). I did it but once I tried to save the Flow Designer (already added multiple of subflows to Flow Designer), it's failed to save with this below error log. I am not sure how to resolve it?

Rejected large REST payload with content-length = 30431828 bytes. Max allowed: 10485760 bytes.

Hey,

Do you have any REST step in this flow designer, in that case:

glide.rest.scripted.max_inbound_content_length_mb	10	The maximum size, in megabytes, for a scripted REST request body that is not gzipped.
glide.rest.scripted.max_inbound_gzip_content_length_mb	1	The maximum size, in megabytes, for a scripted REST request body that is gzipped.
glide.rest.max_content_length	10	The maximum size, in megabytes, for a scripted REST request body, whether or not it is gzipped. Maximum: 25 As a result, even if glide.rest.scripted.max_inbound_content_length_mb or glide.rest.scripted.max_inbound_gzip_content_length_mb are set, the request body is limited to the value of glide.rest.max_content_length.

Update the highlighted one

Hi Bird,

There is a maximum length set on REST.

The title of the Now Support page is different but the cause and the resolution should be the same. Create property "glide.rest.max_content_length" and increase the maximum size of REST data.

Will it impact to system's performance (slow or etc.) once we increase it?

Try to use streaming instead of object.
