Fail to send the completion email #3080
Description
Description of the bug
I created a new project via nf-core create (v2.14.1) and run the template pipeline with
nextflow run . -profile test,conda --outdir results --email [xxx.email.com](http://xxx.email.com/)
command on both nextflow 24.4 and 23.4 but the email cannot be delivered. I manually tuned the code and find that sendmail_html variable has length = 0, so it seems the html render engine (groovy.text.GStringTemplateEngine) has some problems behind.
def max_multiqc_email_size = (params.containsKey('max_multiqc_email_size') ? params.max_multiqc_email_size : 0) as nextflow.util.MemoryUnit
def smail_fields = [ email: email_address, subject: subject, email_txt: email_txt, email_html: email_html, projectDir: "${workflow.projectDir}", mqcFile: mqc_report, mqcMaxSize: max_multiqc_email_size.toBytes() ]
def sf = new File("${workflow.projectDir}/assets/sendmail_template.txt")
def sendmail_template = engine.createTemplate(sf).make(smail_fields)
def sendmail_html = sendmail_template.toString()
In the meantime, If I created the new project via nf-core v2.8 with the lib directory for addressing the email, there is no such problem.
