Invalid template

[Aida]

Hello dear support team,
We often encounter the error:
     "Unable to process template language expressions in action 'Get_file_properties' inputs at line '1' and column '2136': 'The template language expression 'json(decodeBase64(triggerOutputs().headers['X-MS-APIM-Tokens']))['$connections']['shared_sharepointonline_1']['connectionId']' cannot be evaluated because property 'shared_sharepointonline_1' doesn't exist, available properties are 'shared_sharepointonline, shared_office365'. Please see https://aka.ms/logicexpressions for usage details.'."
     and we can't figure out what the reason is. In Support, there were similar questions and everyone writes that you just need to reconnect the flow. We did so, but after a short time the error returned, please tell us what the problem might be? thank you!

Hi @Aida ,

If you are using the PowerApps button as a trigger, then after you update the Flow, you need to remove the Flow from the Apps, and then add the Flow again, then this problem can be solved. Please check this article and get more details:

https://support.microsoft.com/en-us/help/4477072/best-practices-updating-a-flow-used-by-a-powerapp

When testing Flow, you can click I ’ll perform the trigger action to do the test instead of clicking Using data from previous runs.

In addition, you can choose to solve this problem by exporting Flow as a .zip file, and then re-importing it as a new Flow. After configuring the connection, this problem can also be solved.

Please take a try again and feel free to let us know if the issue still exists.

Best Regards,
