SMACK BANG in the middle of my PAYMENT/SERIAL processor… nd it used to work great :face_with_monocle:
whoever made the change really sucks… i couldn’t find a call flow block to replace it with, and i shouldn’t have to…

WHAT IF I HAD BEEN MID GAME RELEASE WHEN THIS HAPPENED!?
MY SERIAL GENERATOR + EMAIL SEND IS WORTHLESS IF IT’S GONNA BREAK!

We just detected incompatibility in the Codeless Logic.

Some blocks have been marked as “UNKNOWN” because they are beyond the current context and the designer is not able to recognize them.

See the list of the affected blocks:

  • Dynamic Block: Call Flow “SERIAL-FLOW”

HOW CAN I CALL FLOW?
IT WAS WORKING!
I SHOULDN’T HAVE TO UPDATE TO A DEPRECATED VERSION OF EXIST!
SOMEONE PLEASE HELP…
MY WHOLE PROJECT HINGES UPON GAME SERIALS BEING SENT OUT SMOOTHLY.

BUMP! IT’S BEEN > 10 HRS

I STILL HAVE NO WAY TO CALL MY FLOW FROM WITHIN CODELESS,
THE FLOW DOESN’T APPEAR IN THE BLOCKS LIST ANYMORE.

THIS IS A NIGHTMARE. PLS HELP

Hello @JesterOC

Thank you for reporting this issue. We are sorry to hear that you are experiencing this trouble.

On April 23rd, we announced that starting May 11, 2026, FlowRunner would be removed from Backendless to live exclusively at flowrunner.ai.

To help resolve this, we can generate an export of your flow so that you can import it directly into flowrunner.ai. From there, you will be able to call it from your Codeless logic via HTTP. Will this solution work for you?

Best regards,
Backendless Support

Sounds like it should work, however I’m having trouble making a flowrunner account. It wants a business email..
I tried mail.com but it wasn’t seen as a business email.
Gonna try Zoho fer business email and try make an account again

I have set up a business email with zoho.
I was then able to make a flowrunner account.. now i need the export of my flow "SERIAL-FLOW’

Hello @JesterOC,

I have exported the block for you and attached it to a private message. Please check it here: https://support.backendless.com/t/re-codeless-unknown-block-previously-it-worked/20239

Please let us know if you run into any other issues

I tried the link.. it opened a Gemini page and a popup said the chat no longer exists or is unavailable

It also said
This conversation was created with a Gem that has been deleted. Create a new Gem or start a new chat to continue.

Edit: I found the permission link for the message in my email

In the private message you tried upload the json, but it doesn’t go to it when i clink the link.
clicking link produces this

Can you please paste the json into a message in the private message you invited me to…
The json link doesn’t work and it’s been 2 days

10

Sorry for the inconvenience. I have edited the message and pasted the fixed link in a private message.

I imported the flow and jumped into edit mode to assign extension nodes to fix it up, but it wants me to login for OAuth and the login button does not work. I tried the button but the page doesn’t work

12

Since flowrunner isn’t working.
How can I achieve the same results with codeless blocks?

I only need to save “PAID” as true, and “SERIAL” as the generated SERIAL value, in the Users table, for the collected identity value i pass in.

Then email serial via template.

Hi @JesterOC

We have fixed login to Backendless account from Flowrunner.

to update a data object in the Users table, you can use one of the following blocks:

2026-06-03 14-35-30

Do I need permission or something to save object in “Users” table?

I did this and it worked brilliantly.

I also did email sending from template in codeless blocks, so no need for flowrunner :smiley:
