Error: CotData does not contain a definition for 'GetCotReportName'

[giogio1]

In NinjaTrader8.0.23.2 64 bits
it appeared this error on a system indicator @COT
I wander why it appeared.
How can I fix it?

@COT.cs:
'NinjaTrader.NinjaScript.CotData' does not contain a definition for 'GetCotReportName'
CS0117 Line 69 Column 16

The offending line is
if (CotData.GetCotReportName(Instrument.MasterInstrum ent.Name) == string.Empty)
and the column 16 is at the GetCotReportName

Thank you.

Thank you for your response.
I noticed that the templates of my 8.0.23.2 platform do not work on another computer where I have the 8.0.26.1 installed.
The error I get in the 26 is "unable to load chart template: the file name.xml was either designed of an earlier version...or not formatted correctly".
I am surprised of such incompatibility with older work,
If I upgrade from 23 to 26 will I lose access to them?
Best

Hello giogio1,

This would depend on what was in the template.

You may need to recreate the template.

On the computer with 8.0.23.2, open charts for each template and apply each template. Save the workspace.
Update to the 8.0.26.1. Then re-save each template. This will update them to the latest version.
Now you can transfer them to a new computer with 8.0.26.1.
