*Datatable* - Configure Columns - "We can't launch this flow because of a variable error" Can't configure columns.

[Mr-Jree]

Steps to reproduce

Steps to reproduce the behavior:

1. Click on Configure Column after already completing the column wizard once
2. We can't launch this flow because of a variable error.
3. Cannot configure columns anymore after the first time.

Expected behaviour

What should happen is this error shouldn't appear when trying to configure a column past the first time.

Actual behaviour

Configure column action bugs and I have to remake the entire datatable if I wanted to change the columns.

Hi Eric,

1. Clickjack protection for VF pages with headers was already unchecked
2. Debug and Development mode were both already unchecked
3. I am a system admin.

Can you confirm the versions of the installed Base Packs?

Here are a few Salesforce bugs that can cause issues:

1. Including a "section" component on your flow screen
2. Trying to save an edited record with a picklist field
3. Trying to update a record with a non custom defined integer field
4. Having any record in your input collection with a value in a geo-location field

[Mr-Jree]

1. 2.17
2. Nope, not doing that here
3. What is a non-custom defined integer field? That's not happening though, just trying to configure columns from a get record element in screen flow
4. No geo-location fields in any records in the input collection.

What version of the FlowScreenComponentsBasePack is installed?

[Mr-Jree]

2.17

[ericrsmith35]

Yes, you have the current version of FlowActionBasePack with 2.17.

You need the current version of FlowScreenComponentsBasePack (2.2.1) to be installed as well.

[Mr-Jree]

I have the 2.2.1 of the FlowScreenComponentsBasePack installed!

Sorry, thought you meant what FlowActionBasePack version I had.

Have you tried creating a simple test flow on a standard object that displays a datatable to see if the same error occurs?

I am getting the same error when trying to show a list of tasks. What I have found is it when I included the subject field from a task, then I cannot launch the configure columns the second time. I have updated to all the latest package versions in my sandbox.
