Sending invitation mail for an event ends with error 500

[asebaste]

Hi there, today I tried to send an invitation mail for an event. I got the error 500. I test the mail seetings as an administrator, it works.
I run version 7.0.7.
Before version 7.0.0 it works. Please find in the attachement the log file. There is something about mails, I think.

Thank you for the support.

Kind regards, Alessandro

Hi Alessandro,

Could you attach custom/Espo/Custom/Resources/metadata/entityDefs/Meeting.json.

[asebaste]

Ther is no such file, I have Account, Call, Case, Contact and Opportunities.
There is such a file in application\Espo\Modules\Crm\Resources\metadata\en tityDefs\Meeting.json

Thank you

Do you have the Invitation template customized? If yes, could you copy it here? Administration > Template Manager > Invitation :: Meeting.

[asebaste]

No, I didn't customized the invitation template. Here it is

Einladung zu {{{eventType}}} '{{{name}}}'


Betreff: {{name}}

Beginn: {{#if isAllDay}}{{dateStartDate}}{{else}}{{dateStart}}{{/if}}

{{#if isUser}} {{#if description}}

{{{description}}}

{{/if}} {{/if}}

Annehmen, Decline, mit Vorbehalt

{{#if isUser}}

Eintrag öffnen

{{/if}}

I could not reproduce.

Could you attach the whole "custom/Espo/Custom/Resources/metadata/entityDefs" directory zipped please?

[asebaste]

Hi, I'm back. Here is the complet content of the requested folder

[yuri]

All data is fine there.

Do you have any 3rd party extensions installed?

[asebaste]

No, there is no 3rd party extension installed.
I hope you have any other idea

I checked the mailadresses from those that should participate at the meeting, the mailadresses are ok.
I also send some mails by using campagne, that worked as well.
But sending an invitation for a event still end in error 500. What does this error code mean?

[yuri]

It looks to me that "orderBy" parameter for some entity in entityDefs is set to non-string non-null value.

[asebaste]

OK, what can I do to test this? Where can I change something?

[yuri]

Please, could you attach the file: data/cache/application/objMetadata.php.
