Error: Signature part configuration excludes this user
This error message means that the user in question is not eligible for any signature.
Solution: Check the target users on active email signatures to ensure that at least 1 signature is made available for the user.
As an alternative, admins can configure a "fallback" signature listed as the last active signature that is enabled for everyone (no filter applied). In case some end users are accidentally excluded from other signatures, these end users would still be eligible for the fallback option.
Error: The 'src' property of the image is required
The ‘src’ property refers to the location where the image or logo is being pulled into the signature.
Solution: Use ctrl+F to search for ‘src’ to identify the line where the output is missing. Images are required to be inserted from a data source in Templafy (utilizing an HTML HTTPS image URL link isn't supported).

Error: The value ‘{binding}’ is invalid. Only binding expressions are allowed as the value of the src property of an image
This error brings attention to the value encapsulated in the curly brackets of the 'src' property and suggests that the binding is incorrect. The expression could take many forms, some of the common examples are as follows:
src='{{DataSources.DataSourceName["ImageName"].DataSourceColumnName}}'
src="{{UserProfile.UserProfileField.DataSourceColumn}}"
src='{{DataSources.DataSourceName[UserProfile. UserProfileField]. DataSourceColumnName }}'
Solution: Review the binding in question based on the forms the binding expressions can take mentioned above. Pay close attention to the use of singular and double quotes, punctuation and spacing between values.
Error: The data source item was not found in the data source
This error occurs when a specific row/column being referenced cannot be found. It is typically caused by incorrect capitalization or a spelling mistake.
Solution: Locate the binding containing the error by using crtl+F and searching for the item name. As seen in the example above, check the spelling of the value in {{DataSources.EmailSignatureIcons[“Templaf large”].Icon}}
Error: The maximum allowed size of a linked resource was exceeded
The resource refers to the image that exceeded the maximum allowed size of '1MB'.
Solution: Identify the image in the signature that caused the issue and use those bindings to pinpoint the data source where the image resides. Resize the image to smaller than 1MB and replace the original by editing the data source item.
Error: The type of the resource is not supported
The resource refers to the image of which the file type is not supported. Supported image formats are .png and .jpg
|
Solution: Identify the image in the signature that caused the issue and use those bindings to pinpoint the data source where the image resides. Convert the corresponding image to a supported file type (.png or .jpg) and replace the original by editing the data source item.
Error: Image contains more than one of the same property
The attributes src, alt, width, and height are the only allowed attributes on the image tag. This error message suggests that some of these attributes have been used more than once.
Solution: The warning message displayed will provide an indication of what property was used more than once. You can use ctrl+F to search for the suggested duplicated property and remove it from the image tag.
Error: The width or height property of the image is required
The attributes src, width, and height are required on the image tag. This error message suggests that some of these attributes have not been specified.
Solution: Use ctrl+F to search for ‘src’ to identify the line where the attribute is missing. Then insert width="x" and/or height="x" with the desired ratio.
Error: The width or height property of the image must be a number, with no unit specified
This error message suggests that the specified attribute does not refer to a valid value. The expected output in width and height attributes is a number, or a dynamic reference to a data source that contains those numerical inputs.
Solution: Use ctrl+F to search for ‘width’ or ‘height’ to locate the line where the attribute is found. Then replace the invalid value with numbers (ex. width="150" height="40"), according to your image ratio requirements.
Error: The link of an image is shown in brackets []
This error occurs if the link (<a href>) of an image is not in proper https:// format.
Solution: Ensure the link is in proper https:// format. If the link is pulled from a User Profile field, it would be a good idea to add a disclaimer for proper format.
