# Resolve flow error: unable to process template expressions

---

When authoring solutions in Flow or LogicApps, you may receive the following error, or a slight variation as every Flow is different:

```

Unable to process template language expressions in action ‘Convert_HTML_to_PDF’
inputs at line ‘1’ and column ‘2336’: ‘The template language expression
‘json(decodeBase64(triggerOutputs().headers[‘X-MS-APIM-Tokens’]))[‘$connections’]
[‘shared_muhimbi’][‘connectionId’]’ cannot be evaluated because property
‘shared_muhimbi’ doesn’t exist, available properties are ‘shared_sharepointonline,
shared_onedriveforbusiness’. Please see https://aka.ms/logicexpressions for usage
details.’

```

Although there is a reference to Nutrient in the error, the problem itself is unrelated to our software. The problem is most likely caused by the Trigger (usually PowerApps). You will need to disconnect and reconnect the trigger for everything to start working again.
