# SpEL expression issue- Must be of type string- "integer"

### Issue <a href="#issue" id="issue"></a>

Error noticed: `spec.endpoints.metricRelabelings.replacement in body must be of type string: "integer"`This error indicates that replacement expects a string instead of an integer. In the CRD some values may contain Regex expressions like `${}`. These characters in Spinnaker are used to evaluate SPEL expressions. There is a way to escape these characters but doesn't work for numbers at this time.

### Cause <a href="#cause" id="cause"></a>

Spinnaker is evaluating the expression and returning an integer causing the error.
