Hi!

I have a trouble with my flow. Im getting an error: Flow save failed with code 'WorkflowOperationParametersExtraParameter' and message 'The API operation does not contain a definition for parameter 'item/itemname.

So I want to use "Add a row into a table" function. I have composed table, and JSON code, Add row function recognizes my file well, but after setting all up im getting that error.
After removing this column ([Pierwotne/konsekwencje]), everything run smooth, but this column is kind important.
The weird thing is that I use everywhere "/" as separator, but in error "." is used.

Do you have any ideas?

JSON code fragments:

Hi @Olut11,

Try switching to the old designer, the new one is quite new and I've already encountered unexpected issues that I haven't encountered before with already designed flows which I fixed by switching back to the old designer. I haven't delved into these issues yet as it works with the old one.

Yea, it is preety weird but changing to old designer worked.
Also I deleted the "/" in column name by script, beacuse I think it created some trouble.

Thank you!

Hi @Olut11,

Yes, I also don't use special characters in my column names, I also exclude spaces and accents.
Tip: I create the column without spaces nor special char and then rename it with them, this way the internal name of the column which is used by http requests (or Power Automate actions) is clean but users see a column name that is more natural to them.

@SamLed Very helpful tips. I follow same method while creating new columns in SharePoint list/libraries.

@Olut11 @lenap Here are few best practices for naming SharePoint columns:
Use only alphanumeric characters, avoid using special characters
Avoid column names beginning with numbers.
Avoid spaces in column names
Avoid reserved keywords in SharePoint
You can find more information about best practices and how to find the correct internal name of your SharePoint list/library columns at: How to find the Internal name of columns in SharePoint Online?

PSA
As of 5/24/2024 bug is still active. Switching to old designer works as recommended.
