is anyone can help please?

[malgokiel]

Hi @Shuhrat_N,

Please try to resave the workflow - change something small in it and save it again.

If it does not work, create a duplicate of the workflow, change it’s name, save it and try to activate that one.

It is difficult to say what went wrong, but because the execution works as expected it might be connected to how the workflow is saved in n8n’s memory.

Hope this helps,

Gosia

Hi @malgokiel ! this is very good that you reply to me, appreciate that. Actually I did try all the mentioned actions as by default but still does not work. So the last hope to re-create the flow once more, I think it will be fastest solution that searching somewhere in the n8n memory)). Thanks one more time!
